For users who see a timeout or parse error after clicking Update Subscription, or whose node list stays empty afterward. Keep any working nodes, then determine whether the issue is with the request, the response format, or list filters. Change one setting at a time and retest the same subscription group to pinpoint whether the cause is the URL, network, format, or display settings.
First, pinpoint where the update fails
Updating a subscription is not a connectivity test for its nodes. v2rayN first requests the subscription URL, parses nodes from the response, then processes them according to the group settings and adds them to the server list. A URL that opens does not guarantee its contents can be imported, and imported nodes are not necessarily reachable. “Update successful” and a successful latency test are two different results.
- Look for the group name, timestamp, and nearby error in the log or information area at the bottom of the main window. Layouts vary, so focus on entries added after the update.
- Open “Subscription Group” → “Subscription Group Settings” and note the group’s URL, filters, and update settings. Don’t delete the group first, or you may lose information needed for comparison.
- Update only the affected group. If the menu only offers Update All Subscriptions, use the group name in the log to identify its result; a successful entry for another source doesn’t mean this group updated successfully.
- Note the number of nodes before and after updating. Start troubleshooting node connections only after the count goes from 0 to a nonzero value. If it stays at 0, keep checking the response and parsing.
Invalid URL: Check the subscription endpoint and HTTP status
Go to “Subscription Group” → “Subscription Group Settings,” select the affected group, and check its URL. Paste the full subscription URL supplied by your provider—not a user dashboard, purchase page, or individual node share link. Check for trailing spaces, line breaks, or non-English punctuation, and make sure query parameters containing & haven’t been truncated.
A subscription URL can stop working after a token reset, account expiration, or service migration. The fact that it worked before doesn’t mean it still works. First check the subscription status in your provider’s dashboard, then copy the endpoint again. Update only the affected group; don’t replace the URLs in every group with the same one.
Error: Response status code does not indicate success: 401 (Unauthorized).
Cause: The server rejected the credentials for this request, often because the token has expired or the endpoint requires a login.
Fix: Get a subscription URL from your account dashboard that the client can request directly. Replace the group URL and try again.
Error: Response status code does not indicate success: 403 (Forbidden).
Cause: The request was denied, possibly due to account permissions, network restrictions, or site security rules. This status alone doesn’t prove the subscription has expired.
Fix: Check your account status and the endpoint requirements, then test both direct and proxy updates. If access is still denied, contact your provider with the status code and time of the error.
Error: Response status code does not indicate success: 404 (Not Found).
Cause: The requested path doesn’t exist. The URL may be incomplete, the endpoint may have moved, or the server may use this status to hide an invalid token.
Fix: Copy the complete endpoint again. Don’t construct the path yourself or replace only the domain while keeping the old parameters.
These are common HTTP error messages; wording can vary with the interface language and runtime, so use the status code to guide your diagnosis. Opening the subscription URL in a browser is only a clue: the browser may have a login cookie, while the client’s subscription request usually won’t inherit that session. If the browser shows a login or access verification page, it hasn’t retrieved the node data.
Update timed out: Compare direct and proxy updates
In the “Subscription Group” menu, look for “Update All Subscriptions (without proxy)” and “Update All Subscriptions (through proxy).” Some versions offer the same options for the current group, with slightly different wording. If possible, compare results for the affected group only. These options control how the subscription is fetched; they don’t change the nodes’ protocols or route all applications through a proxy.
| Result | Likely cause | Next step |
|---|---|---|
| Direct fails, proxy works | The current network can’t reach the subscription endpoint directly | Keep working nodes and update through the proxy |
| Direct works, proxy fails | The proxy node is unavailable, or the endpoint blocks its exit IP | Update directly first, then troubleshoot the proxy connection separately |
| Both methods return 401 or 404 | Likely an issue with the URL or credentials | Get the endpoint again from your account dashboard |
| Both methods time out | Check DNS, the access route, and service status | Try another network and note any hostname resolution errors |
“Update via proxy” requires an already working proxy connection. Select a working node in the main window, set it as the active server, and make sure the core is running. If all existing nodes are down, this option won’t create a connection for you. Use a network that can reach the endpoint, or ask your provider for a working recovery method.
Bottom line: Change only the update route—not routing settings
Try one direct update and one proxy update for the same group, then compare the new log entries. If either method retrieves content that can be parsed, use it to restore the subscription first. Don’t change TUN, DNS, and routing rules at the same time, or you won’t know which change fixed the issue.
Response received, but no nodes parsed
An HTTP 200 means the request received a successful response; it doesn’t guarantee that the response body is a subscription. A user dashboard in HTML, an expiration notice, an access verification page, or even an error in JSON can all return this status. Switching nodes repeatedly won’t help here; focus on the response format.
- Identify the response type: Check the start of the content with a local text viewer. If you see
<!DOCTYPE html>,<html, or a login prompt, resolve the endpoint or access issue first. Don’t import a web page as a subscription. - Choose a supported format: Select a v2rayN-compatible subscription from your provider’s export page. Common formats include newline-separated share links or those links encoded in Base64. You can’t make other structured configurations compatible just by changing the file extension.
- Distinguish share links from subscription URLs: Content starting with
vmess://orvless://is usually a node share link. Import it from the “Servers” menu’s clipboard option, rather than entering it in the subscription URL field, which makes an HTTP request. - Troubleshoot partial parsing failures: If only some nodes are missing, check their protocols, transport settings, and client compatibility. One failed entry doesn’t mean the entire subscription is invalid.
If you copied the response text manually, check for code fences, explanatory text, or incomplete encoded content. Base64 is an encoding method, not proof that a subscription is valid. Successful decoding doesn’t guarantee that every share link has valid fields. Don’t submit subscription URLs or raw content to unknown online conversion tools; they may contain credentials that grant full access.
Certificate error: Check your system time and network
HTTPS subscriptions require a successful TLS connection. If your system date is significantly off, a certificate may appear not yet valid or expired. In Windows 11, go to “Settings” → “Time & language” → “Date & time,” check “Set time automatically,” then select “Sync now.” Also check your time zone and displayed time; changing the time zone alone doesn’t synchronize your system clock.
Error: The SSL connection could not be established, see inner exception.
Cause: The TLS connection failed. Possible causes include the system clock, certificate chain, network interference, or server configuration. Check the inner exception for more detail.
Fix: Correct the system clock first, then check the certificate warning for the same URL in a browser. If it works on another network, check for a captive portal or HTTPS inspection on the current network.
Error: No such host is known.
Cause: The hostname used for the request couldn’t be resolved. This doesn’t mean the node protocol is wrong.
Fix: Check the subscription domain spelling, complete any public Wi-Fi sign-in, then test whether the domain resolves on another network.
If your public network requires a browser sign-in, complete it first. If your workplace network performs HTTPS inspection, follow the administrator’s instructions for certificate trust. Don’t install root certificates from unknown sources. “Allow insecure” in a node’s settings applies to that node’s connection; it isn’t a general fix for HTTPS subscription certificate errors.
Update completes but the list is empty: Check filters and display settings
First distinguish between “no nodes were added” and “no nodes are visible in the current list.” If the update log shows imported entries but the main window is empty, check the selected group and search box first: switch to the updated group, clear the search, and check the list again. An old search term can make newly named nodes appear to vanish.
- Check the group: Go to “Subscription Group” → “Subscription Group Settings” and make sure the updated URL belongs to the group you’re viewing, not another group with a similar name.
- Temporarily clear subscription filters: In the group editor, check any alias or regular expression filter fields. Copy the original values, then clear them and update again. Field names vary by version.
- Retest with one condition at a time: Add one filter condition at a time when restoring your settings. In a regular expression,
^means the start and$means the end. If the provider renames nodes, an overly specific expression may no longer match any of them. - Check the remaining node count: If nodes reappear after clearing the filters, adjust the filter rules. If the count is still 0, check the response format and parsing log instead of continuing to search the display settings.
Subscription filters and routing rules do different things. Filters determine which nodes are included in the update; routing rules determine which outbound connection traffic uses after a connection is established. Changing “Routing Settings” won’t bring back nodes excluded by a subscription filter. Check whether a field keeps matching entries or excludes them before reusing a rule—the two behaviors are opposites.
Common questions after restoring a subscription
Why does the subscription open in my browser but fail in v2rayN?
The browser may have an active login session or use a different proxy route. First make sure it shows node data, not your account dashboard. Then compare v2rayN’s direct and proxy update results. Check browser access and client access to the subscription separately.
Can I update through a proxy if all my nodes are down?
You can only use a proxy to download the subscription if that proxy connection works. Test an existing node first. If they all fail, try another network that can reach the endpoint or ask your provider for a valid endpoint. Repeatedly clicking Update via proxy won’t bypass a broken connection.
Why do my nodes still time out after an update succeeds?
A successful subscription update only means the URL was requested, parsed, and added to the list. Next, select a node and run a real connection latency test, then check the core log. An offline server, expired node credentials, or incompatible transport settings require connection troubleshooting. See the advanced guide.
What information should I include when asking for log help?
Include the client interface type, operating system, update time, results for direct and proxy updates, and error lines with sensitive details redacted. Keep the HTTP status code and exception type. Hide subscription tokens, account details, node passwords, and full share links; there’s no need to publish your entire configuration.
Once you’ve found the cause, keep the working update method and confirm that a normal update succeeds again. Resume automatic updates only after manual updates are reliable, so scheduled tasks don’t keep requesting an invalid URL. To review group setup and import steps, follow the configuration guide.
