I have a site that’s been happily working on Gitlab pages on Gitlab.com for many months now. I had a report that the TLS/SSL certificate wasn’t working any more and when I checked it looked like the certificate was expired.
Logging into Gitlab it said the certificate was expired and “Something went wrong while obtaining the Let’s Encrypt certificate” so I followed the instructions and clicked Retry. The site sat in, “GitLab is obtaining a Let’s Encrypt SSL certificate for this domain” for over and hour so I removed all the domains and added them back. I had to update the DNS records so they revalidated, which succeeded, but it’s again been over and hour and still no certificate.
What else can I do to debug this problem? Is there any way I can find out why this suddenly stopped working so it doesn’t happen again?
Thanks!
