Single Sign-on Login Issue

When end user is trying to connect to Epicor system is throwing below mentioned errors

Error-1.PNG

Error-2

anyone can suggest solution will be helpfull.

First try to ping Server from CMD, it’s reachable or not.

I have verified that we were unable to ping server but few minutes later it will be working fine. This issue is coming every 40 to 45 minutes later continuously.

If you use SSO check your directory service. If using SSO Epicor doesn’t handle credentials.
