### Bug description

Trying to mount an external Webdav storage. Nextcloud is behind a proxy to connect to the internet, but the webdav storage is in lan. No matter how I configure `proxyexclude`, the connection always made to the proxy.
Same with smb connections when trying to mount smb shares.
If I remove the proxy configuration completely, everything is working fine.

### Steps to reproduce

1. Try to mount a local external storage with a proxy configured

### Expected behavior

Proxy should be excluded when connection to targets on the lan

### Nextcloud Server version

33

### Operating system

RHEL/CentOS

### PHP engine version

PHP 8.3

### Web server

Apache (supported)

### Database engine version

### What user-backends are you using?

- [ ] LDAP/ Active Directory
- [ ] SSO - SAML

### Additional info

Tried different configuration setting for `proxyexclude`:

```
"proxyexclude": [
            ".example.com",
            "localhost",
            "127.0.0.1",
            "webdav.example.com:5006",
            "example.com",
            "webdav.example.com"
        ]

"proxyexclude" => explode(',', getenv('no_proxy')),

"proxyexclude" =>
  array (
    0 => '.example.com',
    1 => 'localhost',
    2 => '127.0.0.1',
    3 => 'webdav.example.com:5006',
    4 => 'example.com',
    5 => 'webdav.example.com'
  ),
````
