uMap Docker not accessible after reboot of host system - restart-loop?

[Pfaff15]

Describe the bug I have umap 3.0.2 running on ubuntu 24.04 in docker. After a reboot of the host system, uMap is not accessible. With docker ps it looks like the app keeps restarting all the time. A manual restart of the container with docker compose down and a subsequent docker compose up -d solves the problem. To note is, that this problem always existed on my system, even on older version e.g. 2.7.2.

If there is a mistake from my side, I am sorry. If so, I would be happy to get some guidance. I could not find any solution in the documentation and forums.

To Reproduce Steps to reproduce the behavior:

1. Reboot host system
2. try to access uMap on my system
3. get error no connection possible
4. ssh onto the host
5. docker compose down
6. docker compose up -d
7. uMap running again

Expected behavior After a reboot of the host system, uMap should start automaticaly and be accessible as usual
