I have migriated mailcow to another machine according to this
all but the “main” domain work fine. But for my main domain (mydomain) I get this log in ACME:
2.8.2022, 09:11:15 Cannot match your IP 2001:41d0:701:1000::18a0 against hostname mail.mydomain.com (DNS returned fd4d:6169:6c63:6f77:0000:0000:0000:0011)
2.8.2022, 09:11:15 Found AAAA record for mail.mydomain.com: fd4d:6169:6c63:6f77::11 - skipping A record check
Thanks a lot for any hint where this mismatch could come from !
