Known Issue???

All of a sudden tonight my cwp user panels won't load, they just hang there but if I do a domain.com:20893/user/ I get a 500 error like this?

I have restarted cwp root admin panel which works fine but cwp user panel does not.

Anything could cause the problem (ddos attack, resource overusage, etc).

So I recommend you to check the error logs of CWP for investigation:
https://wiki.centos-webpanel.com/service-log-paths
(see the section "CWP server logs and server services logs, including (PhpMyAdmin/Roundcube/API)")

Yesterday the control panel updated, and today there was an update to the cwp-suphp if you have the CWP repo active.

Did you try to reboot?

Yeah I tried a reboot. The cwp user page comes up I enter my l/p in the fields and submit and it goes to 500 error

Might be that bug popping up.

Try Suspending the client, make sure the suspend page come up, and then unsuspend.
