NGINX - allow `.well-known`

Because of: ``` # Deny access to . (dot) files location ~ /\. { deny all; } ``` `.well-known/something` is also blocked. Some third party services require to place files into the `.well-known` directory to do site ownership verification. --- I did the following: ``` location ^~ /.well-known/ { allow all; } # Deny access to . (dot) files location ~/\. { deny all; } ``` this will: * `.foo` **403** * `.foo/` **403** * `.foo/bar` **403** * `.well-known` **403** * `.well-known/` **403** * `.well-known/foo` **404** * `.well-known/some_exisitng_file` **200**
