For one domain Letsencrypt automatic update fails. For this domain I use the dns service of my registrar, and point this to my server.
In the error message I found that Letsencrypt uses the ipv6 record:
Error: http://mail.mydomain.info/.well-known/acme-challenge/letsencrypt_1586383806 is not reachable. Aborting the script.
dig output for mail.mydomain.info:
mydomain.info.
2a01:4f8:150:2308::2
Please make sure /.well-known alias is setup in WWW server.
Is there a way to force the Letsencrypt auto update to use ipv4?
