Tried this one, still get a 404 on .well-known? I checked /etc/nginx/webapps.conf and the alias seems to be there. I do use custom nginx-templates, but they all include webapps.conf so it should be good?
I get the feeling WordPress is messing things up here, because I tried another site (with a Piwik install) and there were no problems there. Going to investigate this more now.
Make sure you don't have anything like the following in your custom templates, because it'd return 403 error then:
Code:
location ~ /\. { deny all; }
You get 404, so I think it's still related to the alias thing (I can check it directly on your sever if you'd like me to)
