Hey guys,
I installed mailcow a few weeks ago and it works like a charm. The only problem I have is, that the acme container tries to resolve the DNS entries, but every now and then one is failing. It is always the same domain, but I haven’t changed anything on my DNS.
The error message says “No A or AAAA record found for hostname xxx.yyy”, then the system archives the active certificate. Sometimes it works if I restart the acme container, sometimes I also have to restart the unbound container, but today nothing is working
