AlertManager not starting

Hello,
i have a problem with GitLab Version 14.8.2 und the daemon: alertmanager…
I´ve got the following error message:

msg=“unable to initialize gossip mesh” err=“create memberlist: Failed to get final advertise address: No private IP address found, and explicit IP not provided”

I search on several sites and communities, but I can’t find an possible answer. Under GITLAB I find an issue with * ## #3705, but this is NOT working on my system… So, what kind of problem have I here?

Best regards

Z. Matthias

I am seeing similar logs in my single node (no runners, just the primary application in a docker container). I do have it behind a reverse proxy but I have configured the settings in accordance with GitLab’s documentation regarding reverse proxies.

Is this normal? I am not able to discern what needs to be fixed. Here are some logs if anyone can offer any insight, thanks!
