Short summary:  
Debian bookworm server with sury repo for php.  
PHP 8.3 is active (problem also appears with php 8.1 and 8.2)  
using apache2 as webserver  
NC available via nginx proxy

Since the last update I am getting these errors, and I can’t find any source of problems. Currently my Nextcloud instance is available and works, but I’d like to solve these issues:

```

Any Ideas where this problem could come from?

Can you post the output of `occ config:list system` and also manually review your `trusted_domains` value? Is it maybe accidentally a string and not an array? [https://docs.nextcloud.com/server/latest/admin\_manual/configuration\_server/config\_sample\_php\_parameters.html#trusted-domains](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/config_sample_php_parameters.html#trusted-domains)

Even if only one domain is listed, it should still be bracketed.

That said, I’d expect you to have other problems. Unless maybe you only access Nextcloud via [http://localhost](http://localhost)?

```

In Config:

```auto
  'trusted_domains' => 'nc.jhml.de',

```

No Array, but no array needed.

It needs to be an array. Even if it only contains one element:

Ok, didn’t know that. That seem’d to be the fix. That plus making my server now asking the proxy when connecting to itself than trying localhost 😃

Thank you
