Intermittent Connection Issues When Testing Nodes on n8n Cloud

It sounds like the issue you're encountering isn’t specific to one type of node but occurs throughout when testing nodes in the cloud version. While there isn’t a documented, widespread bug causing intermittent test connection failures, here are some troubleshooting steps to consider:

1. Refresh the Workflow or Browser
   Similar to what you’ve already observed, refreshing the workflow canvas or your browser often “resets” the connection state. This suggests that there could be a temporary network or session-related hiccup.

2. Check Network and Browser Stability
   Since the error occurs during testing, ensure that your network connection is stable during these operations. Sometimes browser caches or local network issues can lead to intermittent failures.

3. Review Any Console or Log Output
   If possible, check your browser’s developer console or the n8n logs (if accessible) for any error messages. This might provide hints about whether the connection is being reset by a reverse proxy or there are issues with credentials or parameters.

4. Environment Considerations
   In some cases, reverse proxy settings (if applicable for your setup) or session timeouts could affect test node connectivity. Although these settings are more typically a concern for self-hosted instances, if your cloud workspace has any custom configurations, it’s worth confirming that everything is set up as recommended.

5. Contact Support if the Issue Persists
   Since this is occurring on the cloud version and if none of the above steps help, it might be best to reach out to n8n support. Let them know you’re experiencing intermittent test node connection failures—this feedback is useful if there’s a transient issue on the platform side.

If you have any additional details (error messages, console logs, etc.), sharing them with support could help diagnose whether it’s related to network quirks or a potential platform-related issue.
