No access to web UI of HA in docker anymore

Hi. I run HA in a docker on my openmediavault NAS (Intel PC) for quite a while without problems. Just recently I can’t acsess the HA web GUI. The docker, of course, is running. Other services HA provides do not react either. Mere restarting the docker does not help. The log shows no error:

[fix-attrs.d] applying ownership & permissions fixes...
[fix-attrs.d] done.
[cont-init.d] executing container initialization scripts...
[cont-init.d] executing...

[cont-init.d] exited 0.
[cont-init.d] done.
[services.d] starting services
[services.d] done.

How can I debug this further?

I fixed it by fetching the latest docker HA image and run it with the old config. This seems to work. I’ll just dump the old instance.
