Nothing being returned in N8N

Hello hive, would appreciate some advice!

Our server got upgraded to ubuntu 20.04, and I noticed that in the N8N console nothing’s being returned in the display. Once a flow is ‘executed’, it sits in its ‘executing workflow’ state with the spinning circle of death. I’m also unable to stop the execution. However, the flow is executing where appropriate, and reporting as successful in the executions log.

To try and fix it I’ve done the following:

  • Reinstalled NodeJS
  • Reinstalled NPM
  • Reinstalled PM2
  • Reinstalled N8N
  • Ran N8N in a docker container

I’m not sure what else to try! I don’t even know what’s causing it. Server side it’s running fine and PM2 isn’t reporting any errors. Any ideas where to look?

It was actually an NGINX issue - I had the same issue before and the nginx.conf had reset after the upgrade. Thanks to the post here: Nginx configuration - #7 by Arnaud

For anyone using plesk with an NGINX proxy, simply add the following to the nginx additional directives for the domain/site:

proxy_set_header Connection '';
proxy_http_version 1.1;
chunked_transfer_encoding off;
proxy_buffering off;
proxy_cache off;
