Save entity requires authentication every time

[SM_9802787]

ThingWorx Version 9.4.0 
Every Time I try to save an entity I have to re enter my credentials. The thing also give an error that it is not running no matter what service I try to run. 
Entity in question is made from the Thingworx Mail extension v. 4.1.1 Thing Template, Configured only no modification from original state. This identical configuration is working on other servers without issue. 

I have removed the extension and restarted the Apache service, then reinstalled and recreated the thing problem persists.

Does anyone know what could cause either of these issues?
