Citrix - CAG Error 401 after user Logs in

[DNM]

Hi Guys,

 

Not sure if this is in the right place... We have a Citrix XenApp server environment for our remote access. Our users have recently started seeing the 401 - Unauthenticated error after logging into the Citrix Access Gateway. I have been looking around on the internet and can't find a solution. Within Windows Event Viewer I am seeing the following error;

 

Site path: C:\inetpub\wwwroot\Citrix\CAG.

A communication error occurred while attempting to contact the Access Gateway authentication service at https://gateway.aatm...thService.asmx. Check that the authentication service is running. The message reported by the underlying platform was The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.. [unique Log ID: 7a3270ce]

 

Does anyone have any idea as to what is going on and how I can go about fixing this issue?

 

Kind Regards

Hi, I have managed to fix the Certificate part but now i have an issue with the Authentication Service.

 

The issue for the SSL/TLS was a missing intermediate certificate for Rapid SSL.

 

Once I installed the intermediate certificate the SSL error wwnt but a new error occoured, which i will post the error in the morning.

 

Kind Regards,
