[Let's Encrypt] HTTP validation failed

omexlu

Hello,

After I installed the update “Version: 2022-06” today, the following errors occur in the “ACME” (all AAAAs affected):

06/17/2022, 08:13:12 mx.s3cured.pw - Confirmed AAAA record with IP 2a01:04f8:1c0c:789d:0000:0000:0001, but HTTP validation failed
06/17/2022, 08:13:12 mx.s3cured.pw - Found AAAA record for mx.s3cured.pw: 2a01:4f8:1c0c:789d::1 - skipping A record check

Is there a known bug after the latest update because of IPv6 (it was disabled?) or did I reach a rate limit because I had to restart the server a few times because of updates and other things.

Thanks in advance.

PS. Nothing else was changed except the update and Docker Compose v2 was installed.

omexlu Is there a known bug after the latest update because of IPv6 (it was disabled?)

https://mailcow.github.io/mailcow-dockerized-docs/de/i_u_m/i_u_m_install/#installation-von-docker-compose-v2

The web interface will only be accessible via v4 by default in the period from June - December 2022.
The reason for this is the dual compatibility between Compose v1 and v2.
Should you wish to access the web interface, as before by default via v6, please take a look at this chapter.
The 2022-12 update will restore the native IPv6 reachability from the UI.
