Describe the problem/error/question

Over the last 2 days, I have been receiving “Connection Lost” messages a few times a day. Is this normal? Is it a system issue?

What is the error message (if any)?

Information on your n8n setup

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Connection loss on what? From you to n8n? Or from n8n to another service? Other service could be “normal” if its under high load.

I have no idea, it just says “Connection Lost”

I thought it meant connection to n8n, which is what I suspect is the case because all I did was refresh the screen, I didn’t try to run the workflow.

FYI it’s the hosted version of n8n

Yeah I believe this indicates a connection loss from you to the self hosted instance.

We have solved similar issues before, and it was related to nginx reverse proxy not correctly configured to handle the web socket n8n communicates on.

What is your current setup look like? Are you behind a domain name? nginx reverse proxy?

I am using the cloud hosted version of n8n, not self hosted. and it is still down even as of a few minutes ago.

Ah, I see where I misunderstood. I assumed hosted meant self hosted. Usually we use cloud vs hosted as nomenclature.

Do you use any adblock or local caching extensions? Does the same occur in incognito mode, and other browsers? What about on a VPN? Same thing?

No worries, I tried an incognito window and it worked. So I decided to reboot my machine and now it works. So now I may need to reboot when this happens again. Thanks for your help!

Thanks for bringing this up. “Connection Lost” messages usually indicate a temporary issue with your network connection, server performance, or the n8n backend timing out. It’s not normal if it happens frequently throughout the day.

To help diagnose this:

  • Are you running n8n on Docker or shared hosting (like Hostinger)?
  • What’s your EXECUTIONS_PROCESS setting? (own vs main)
  • Are there any memory spikes or CPU overloads when this happens?

Feel free to share your setup details and I’ll help you pinpoint the issue. In the meantime, restarting n8n or checking server logs might reveal more.
