Can’t update settings

With DEBUG enabled, I get nothing. There were a lot of Deprecated messages, then I deactivated all plugins throwing such messages to get a cleaner output. Then when I click “Check again”, no output at all. This staging server is running PHP 8.2.

Yes, that is one of the first things I did. I verified still active in the AWS console. Interestingly enough, I went into the staging server again this morning and find the status green with the message ‘Storage provider is successfully connected and ready to offload new media.’. However, if I click ‘Check now’, it turns red and gives the message I originally posted.

The Media Library continues to function without issue offloading media uploaded.

Thanks for the help. Nothing was found in the console of the browser while loading the page or selecting ‘Check again’. What is the best way to send the downloaded diagnostic info?

On our staging server, I’ve deactivated all plugins other than this and switched to the Twenty-Twenty-Three theme. The issue persists.

$ grep AWS wp-config.php
define( 'AWS_ACCESS_KEY_ID', 'aws key' );
define( 'AWS_SECRET_ACCESS_KEY', 'aws secret' );

Took another look at the DEBUG log and browser console and found nothing. Is there somewhere in AWS I can see related logs?

Adding the AS3CF_ prefix did not work, the same result. If I choose to store the key and secret in the database, all works. I didn’t know about my wp-config settings being legacy, are the AS3CF_SETTINGS recommended? But there are some AS3CF_SETTINGS I’m not sure of the proper setting. Perhaps you have another document that will answer these questions? …

key-file-path – is this expecting a JSON value or to generate?
use-server-roles – I assume this should be false if I’m using key/secret?
delivery-provider – this should be aws? In my GUI, I see this set to Other, but the other CDN field is blank.

Nonetheless, if I use AS3CF_SETTINGS in place of the key and secret in the wp-config file, it detects the settings but keeps refreshing back to the Storage Provider page with a refresh link when Save and Continue is selected.

define( 'AS3CF_SETTINGS', serialize( array(
    'provider' => 'aws',
    'access-key-id' => 'my key',
    'secret-access-key' => 'my secret',
    'key-file-path' => '/var/www/aws.json',
    'use-server-roles' => false,
    'bucket' => 'my bucket',
    'region' => 'us-east-1',
    'copy-to-s3' => true,
    'enable-object-prefix' => true,
    'object-prefix' => 'wp-content/uploads/',
    'use-yearmonth-folders' => true,
    'object-versioning' => false,
    'delivery-provider' => 'other',
    'delivery-provider-name' => '',
    'serve-from-s3' => true,
    'enable-delivery-domain' => true,
    'delivery-domain' => 'cdn.domain.org',
    'enable-signed-urls' => false,
    'signed-urls-key-id' => '********************',
    'signed-urls-key-file-path' => '/path/to/key/file.pem',
    'signed-urls-object-prefix' => 'private/',
    'force-https' => false,
    'remove-local-file' => true,
) ) );
