[image] smith: 1.79.3 I got the “Connection Lost” error as soon as I updated to version you’re on, 1.79.3. So I downgraded back to 1.78.1 and everything’s been working fine since. There seems to be an issue with that version.

I am using NGINX Proxy manager as a reverse proxy. Had to enable websocket support. Then it started working again - also with the latest version 1.80.x

where can i find the environment / configuration file in ./public_html/node_modules to change setting ``` N8N_PUSH_BACKEND=sse

Hi where can i find the configuration file to change this setting?

Hi @Erik_Augustin , If you use Docker, you can set this in your Docker compose file.
