Hello All,
I have a self-managed full Camunda 8 stack.
All of the components working I think except one: webmodeler-websockets
Is it running, but the logs of this container:
“Starting the WebSocket server on port 8060…”
This log present just, after like 24 hours too. Nothing else.
Is it normal? And the related ingress URL → point to 404 page
Domingos_Dias
Do you have idea?
Thanks a lot
Can you show the full log?
Can you share your configuration file?

Your configuration file doesn’t seem to have anything wrong, the strange thing is that there is no error in the log, it just stays in the starting state as I understand it, have you checked that there is no service port conflict?
I think you can use: APP_DEBUG: “true” in the environment variables, at least that’s how I do it in docker
