I get the following error in the domain's log:

I have tried PHP 7.4, 8.1 and 8.2 but get same results. I have Yourls hosted on Apache 2.4, behind Nginx Proxy Manager. The SSL cert is on NPM which redirects traffic to the Yourls host on port 80.

My site URL starts with https in /home/yourls/public_html/user/config.php: define( 'YOURLS_SITE', 'https://example.com' );

Anyone have any ideas how to troubleshoot this? Is there something I need to add or change in the config?

Turned out to be a weird issue caused by migration of the website/database. For whatever reason, I had to "change" the password of the database user even though it was correct. I used the same password when I "changed" it. Appears to be a known bug when migrating from one server to another. To be clear, this was not a Yourls issue.
