Connection lost on Workflow - apache2 reverse proxy with traefik

[dontheT]

Hi,

we are trying to setup our new n8n environment for the first time.

Our setup:
We have one external ip where we have already a apache2 web server in charge of all http/https request. Our n8n programmer is in charge of the n8n vm which uses traefik to redirect the traffic to the n8n container.

traefik:v3.4.1                  "/entrypoint.sh trae…"   12 days ago   Up 15 hours   0.0.0.0:80->80/tcp, [::]:80->80/tcp, 0.0.0.0:443->443/tcp, [::]:443->443/tcp   traefik

We still facing the issue that the connection is lost every second. For a part of a second the connection is ok and suddenly the connection is lost again.

Here are our config from there apache2 web server:
