Summary of the issue you are facing:

I cannot resolve the “trusted_proxies“ setting is not correctly set, it should be an array of IP addresses error in the Admin Overview.

This is the array in my config.php file, why does it not work?

‘trusted_domains’ => [‘localhost’,‘cloud.shearer.au’],
‘trusted_proxies’ => [‘127.0.0.1’,‘172.19.0.1’],
‘forwarded_for_headers’ => [‘HTTP_X_FORWARDED_FOR’,‘HTTP_X_REAL_IP’],
‘overwritehost’ => ‘cloud.shearer.au’,
‘overwriteprotocol’ => ‘https’,
‘overwrite.cli.url’ => ‘https://cloud.shearer.au’,

Cerbot certificates are all installed and valid.

Captain ChatGPT has been unable to resolve either

Thank you for you help

Hey @Andy_AU welcome to the Nextcloud community :waving_hand:

Trusted proxy configuration

When you’re running Nextcloud behind a proxy it needs to know about the proxy.

Set trusted proxies (iterating values 0, 1, 2…):

occ config:system:set trusted_proxies 0 --value="your.reverse.proxy.ip"
occ config:system:set trusted_proxies 1 --value="your.other.proxy.ip"
occ config:system:set trusted_proxies 2 --value="another.reverse.proxy.ip"

your array should look something like this:

  'trusted_proxies' => 
  array (
    0 => 'your.reverse.proxy.ip',
    1 => 'your.other.proxy.ip',
    2 => 'another.reverse.proxy.ip',
   ),

Can you provide more context? Are you attempting to customize trusted_proxies?

You may want to check the fully parsed (and non-censored) output by running occ config:list system --private. And perhaps posting the censored version if still stuck (occ config:list system).

Since you mentioned AIO, are you perhaps using podman rather than Docker? "trusted_proxies" setting is not correctly set · Issue #5221 · nextcloud/all-in-one · GitHub

The Nextcloud Admin Manual has fairly extensive coverage of the config file format.
