I wasn’t sure if this was worth a new thread, but need to ask. I’ve been using
certbot-auto on my CentOS 7 machine for a couple months now with no problems, however two days ago it stopped working (or so I thought). Today when trying to download it again via wget I noticed that the IPv6 version was failing via time out and then the IPv4 succeeded. How can I go about diagnosing the issue?
Everything works, but I have to wait 2 minutes or so for the IPv6 contact to time out and then the IPv4 tasks go quickly.
