    Hello,
    My name is David Barczak. I work for the University of Delaware and I have been using Authorizer for a few years now and love it. It has made hooking into CAS so much easier. Unfortunately since I upgrade my wordpress site to wordpress 5.9.1 Authorizer is slowing down my site to the point of it crashing. I am having a problem using it. I keep getting a message that says “Can’t reach CAS server. Please provide accurate CAS settings if you intend to use it.” I have not changed anything and it was working just fine before WordPress 5.9.1. Now I get this message. I try to turn off the plugin and it is difficult but I am able to and then I turn it on again and it is ok for a day and then it slows down my site and I get this message again. Can you help?

    Aloha, there must be something else going on, we are running 5.9.1 on several hundred WordPress servers and haven’t seen any issues.

    Do you have any insight into the WordPress server itself? Error logs or checking to see whether the slowdown is related to heavy load, or simply waiting for the CAS server to respond and timing out after 60 seconds or so. That would help troubleshoot what’s going on.

    If Authorizer is reporting “Can’t reach CAS server” then perhaps some firewall rules were changed on the CAS server itself? At our institution our central ITS restricts access to the CAS server to a whitelist of allowed domains, so it’s possible your WordPress server actually can’t reach the CAS server due to some configuration change.

    Authorizer uses wp_remote_get() to test reaching the CAS server, so that would be another thing to test.

    https://github.com/uhm-coe/authorizer/blob/master/src/authorizer/class-helper.php#L367-L380

    You can try to see the output of wp_remote_get( 'https://your-cas-server:443/cas/serviceValidate/' ); in a wp shell session (using WP-CLI) on the server to see if there are issues reaching the CAS server. Or try to ping it or use curl to inspect the output.

    Paul,
    Thank you so much for reaching out to me. I really appreciate your help. To be honest I am a novice and I understand enough to be dangerous. What you have written is a bit above my head.

    I did think that it should be a different plug in that could be causing this issue and forcing it not to work so I turned off Autoptimizer and that seemed to work. I am still making sure that this was the cause to interrupt Authorizer but it seems to be the ticket. Thank you very much!
