Hello, I'm running n8n within a docker container. It is accessible via subdomain and reverse proxy. I placed the Apache Directive below which does the trick to access n8n via https://n8n.example.com # Exclude ACME challenge from proxy <Location "/.well-known/acme-challenge/"> ProxyPass ! </Location> # Proxy everything else ProxyPreserveHost On ProxyPass / http://localhost:5678/ ProxyPassReverse / http://localhost:5678/ I can connect n8n to external services like Paypal or Mautic. The problem I'm experiencing is that when I'm trying to execute a workflow I'm receiving the following error from the n8n backend: "Problem running workflow Lost connection to the server" After searching the web I found out that it may be because of websocket issues. Has anyone here experienced similar problems and has a solution? Many thanks Christian
