Hello, in my server I am using certbot successully. I have several sites and all are ok. Apart from one. The DNS A are configured correctly and the site is working fine since half year. However Certbot certonly is giving an error: - The following errors were reported by the server: Domain: my…

Add listen 443 ssl; to both of those server blocks. Maybe it is falling through to the other domain because it’s the only one explicitly listening on ssl.

From my knowledge I don’t. Why you ask? It’s strange that it’s happening only with this site, not with others in the same server. None of my sites have an AAAA record configured, but I am not 100% sure if in Arubacloud vps I have an IPv6 or not

Let’s Encrypt recently changed to preferring validations over IPv6 if a site has an AAAA record. Many people’s sites, it turns out, do have AAAA records but are not properly set up to receive incoming web connections via IPv6.

What should I check then? In the domains DNS configurations there re only MX, A and TXT records.

Since there’s no redirect from mysite.pl to myanothersite.pl in your nginx config, I’m guessing that redirect is happening in your PHP code. Your nginx config looks like it should send a real file if it exists before executing PHP, so the first thing to check is that the file .well-known/acme-chall…

really strange. I didn;t change anything yet in the server or DNS. Few minutes ago I tried to enter: http://mysite.pl/.well-known/acme-challenge/wc7Romm8QfnvUMxqn4YnSm48XNeOHGkyvmGPA_8Yb4Q and got redirected to https://myanothersite.pl/.well-known/acme-challenge/wc7Romm8QfnvUMxqn4YnSm48XNeOHGkyvmG…

One thing to check is the possible difference between http://mysite.pl/ and http://www.mysite.pl/; it sounds like they might be configured differently in this regard.

What kind of configuration? The DNS have the same IP address for www and non-www. The rest of the configuration is here above, in the nginx vhost I posted. One more thing I just noticed. I tried to go to https://www.mysite.pl … I get the error that it’s unsecure. And if I accept to proceed, the br…

It’s very inconvenient to look into this without knowing what the actual domain names are; do you think you could let us know them?

I think it was shown (maybe inadvertently): [image] Open Graph protocol The Open Graph protocol enables any web page to become a rich object in a social graph.
