Help... APM logs are displayed on browser as plain text

Folks,

 

I have webex using APM for kerberos Authentication as SSO. When I hit login on the webex home page, it is redirecting me to (which it should), But instead of SSO login, I'm getting browser full of APM logs in plain text intermittently. When i refresh or reload the page, I'm able to login with SSO.

 

Does anyone came across this?

 

Any help is much appreciated! Thanks in advance
