Hopefully this is posted in the right place. I am new here.
I recently added a custom domain to a website in Gitlab Pages. I verified the domain successfuly with the TXT record and pointed my A record to the correct GL Pages IP address. Gitlab Pages reports that my letsencrypt certificates was obtained.
I can access my website without https just fine, but with https I get a “Warning: Potential Security Risk Ahead” error in my browser. It has been almost a full day.
I have another Pages site with the same configuration and everything works fine, though it usually has issues with the letsencrypt auto renewal.
Am I missing something here? Thanks!
I’m having the same issue. Only one of my certificates works. Try all the certificates: I find only one of mine works. I suspect this is a bug.
Are you using Cloudflare? Try playing with the certificate on the Cloudflare side.
I have several GL pages websites. It seems the www subdomain certificates on all of them stopped working at some point, though GL reports they are active and verified. The root domain certs work fine. No, I’m not using Cloudflare.
I just set up a redirect to point www to my root domains, which is good enough for me in my case.
It seem I encountered the same problem, only one certificate is correctly served
Just to add, same here, the certificate contains only one of the aliases and fails for the others. It started failing about a week ago which is odd because the certificate’s validity is from beginning of August through October.
I don’t remember whether the certificates used to contain all the aliases or whether different certificates used to be served from different aliases. Does anyone know?
Hi all - We’ve received some additional reports, so thanks for bringing this up. We’ve started some investigations in this issue. I don’t have much information at the moment but I’d recommend to follow it for updates on our findings.
Some context that might help GitLab to debug: I deleted both domains (petsc.org and www.petsc.org), re-added one (petsc.org), and waited for a new Lets Encrypt cert to be issued, but GitLab Pages is still serving the old certificate for www.petsc.org (even though that domain is no longer listed).

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
This should be fixed now. See this comment. Feel free to ping me if for some reason you are not seeing this resolved.
