[ISSUE]: Connection LOST

[tool_dmvf_ltd]

Hello guys,
after the last update (1.0.5) we continue to get “Connection Lost” message when we try to edit a workflow.

Furthermore when we try to update to the version 1.1.0 (with the usual command below) nothing happen: it remains into version 1.0.5

# Pull latest version
docker compose pull

# Stop and remove older version
docker compose down

# Start the container
docker compose up -d

Let us know thank you

ok, I solved switching on Websockets Support my Nginx Proxy Host

Hey @tool_dmvf_ltd,

You can probably drop the caddy part of your compose file, If you are using nginx proxy manager caddy is probably not really doing anything for you.

I solved my issue putting:

location / {
proxy_pass http://n8n.DOMAIN:5678;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection “upgrade”;
}

in my NGINX configuration file. being struggling with this connection lost issue for 2 hours. heck.
this post helped me, thanks. seems to be really a webhook configuration thing.

probably the same effect of turn on the toggle that @tool_dmvf_ltd toggled

[Jon]

Hey @caio-vinicius,

You got it, that toggle basically does hte same thing. There are other posts on here with the same solution you have used as well
