Yes, your client is trying to connect using IPv6 and failing. This is odd however because we had this problem and then we’ve configured it properly and it was working. This must be some upstream issue from our hosting provider.
Edit: I’ve opened a ticket and waiting for their answer. Thanks for the report!
I'm curious, but how/what is the actual problem there? I can connect over IPv6 just fine, and IPv6 shouldn't make a difference to TLS¹?
(¹in this case)
I’m not an expert on networking but that’s the verdict I get when pasting this problem to ChatGPT. We did have this and went away when we activated IPv6. Firefox and depending on your network/OS you might access the site via IPv6, in which case it will fail if it’s not accessible. I still have problem accessing it locally, curl fails, it works when I am in the network, so I don’t know what’s the case here. It works for some and not for others? Super weird.
same for me in zen browser fwiw
