Description

I have a server, with the name 

~^(?<domain>.+)$

that is supposed to catch any domain, however it works for some domains, and doesn't work for some others.

Here is an example of once working and once not:

2017/04/22 21:30:25 [error] 3941#3941: *3 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 172.68.226.80, server: test.namazso.eu, request: "GET /nonexistent.php HTTP/1.1", upstream: "fastcgi://unix:/srv/www/test.namazso.eu/php-fpm.sock:", host: "skinchanger.download"
2017/04/22 21:30:31 [error] 3941#3941: *5 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 172.68.226.86, server: ~^(?<domain>.+)$, request: "GET /nonexistent.php HTTP/1.1", upstream: "fastcgi://unix:/srv/www/namazso.eu/php-fpm.sock:", host: "namazso.eu"

I only have these servers, with the mentioned being the default:

server_name ~^(www\.)(?<domain>.+)$;
server_name ~^(?<domain>.+)$;
server_name test.namazso.eu;

Please show listen directives from the server blocks in question.

Note that "default server" is a property of a server regarding to a listening socket, and not something global. See ​How nginx processes a request for more details.

Oops, sorry, it turned out that it was a result of a misconfiguration. the regex only listened on 443, which is the only place it is supposed to get requests at all, but

  • cloudflare was misconfigured, thus showing https, but requesting http in reality
  • and test.namazso.eu was listening on port 80 too, alone so was default too, so the request didn't fail.

I can't close the ticket, so i'd be grateful if you could do it.

Sorry for bothering, and thank you.
