Describe the problem/error/question

Encountering Connection Lost Loop. Restart, re-login solves till execute something.

What is the error message (if any)?

Connection Lost

Debug info

Tried to change browsers and networks. Colleague informed no such issue.

core

  • n8nVersion: 2.17.6 (was 2.17.5, updated to see if it will solve)

client

  • userAgent: latest Chrome and Safari Generated at: 2026-04-23T11:29:38.714Z

extent analysis

TL;DR

The issue might be resolved by investigating and addressing the root cause of the "Connection Lost" error, potentially related to the n8n version or browser/network interactions.

Guidance

  • Verify if the issue persists across different browsers and networks to isolate the problem.
  • Check the n8n documentation for known issues or updates related to connection stability in version 2.17.6.
  • Consider downgrading to a previous version of n8n (e.g., 2.17.5) to see if the issue is version-specific.
  • Investigate potential network or firewall settings that might be causing the connection loss.

Notes

The fact that restarting and re-login temporarily solves the issue until an action is executed suggests a potential issue with the application's session management or connection handling.

Recommendation

Apply workaround: Since the issue is intermittent and restarting temporarily resolves it, applying a workaround such as automatically restarting the application or re-establishing the connection after a certain period of inactivity might be a viable temporary solution.
