When attempting to login to our Citrix services web page we receive an "authentication failed" message from the web page and a "SEND FAILED" Radius response from the security server:

原因
Firewall issue
解决办法
Issue was resolved with firewall vendor. A default route had been changed and once put back everything worked again.
