i followed this Tutorial Failed authorization procedure - The server could not connect to the client to verify the domain.
Everything seems straightforward, but at the end i’m failing the DNS Challange due to timeout.
Acme can succsfully create over the Dynu Api the necessary txt record.
But after this “Let’s check each DNS record now.” it fails within 5 minutes.
It retrys it the whole time, but nothing changes.
RspbPi 2 with acme and ddclient
DDNS Service: Dynu
