I've been reciving this error when trying to login via Pulse. I'm not seeing anything in the logs on my end.
I understand the issue, suspect the issue with pulse and host checker, not sure whether you have enabled Hostchecker however the below two knoeldegebase links has more or less majority of pulse issues covered, please go through this. I am sure it will help you.
if the above KB's not resolving your issue, its important for us to look in to user access logs on IC and pulse client side logs.
Note: If I have answered your questions, you could mark this post as accepted solution, that way it could help others as well. Kudo will be a bonus thanks!
If someone is facing this issue again in Jan 2018 on windows OS, you need to uninstall latest security update from microsoft, which is following.
Would updating to the newest Pulse client fix the issue? We had similiar issues and updating the client fixed the host checker rejection.
The problem is with WIndows 8.1 and Windows 10 machines that have updated to Microsoft's January 3rd updates and the Pulse Secure uses Host Checker at realm or role level. It stops the Host Checker call out to happen and rejects connection.
What we did:
Downloaded the 22.214.171.1243 Pulse Secure desktop client installer package
uploaded to our MAG2600 (running 8.2R9 (build 58917))
Advised all clients to connect to their Pulse Secure desktop clients for the upgrade.
-- then advised if it failed, they needed to uninstall and redownload the Pulse Secure desktop client from our VPN home page.
Worked for our folks.
If you are using Pulse Policy Secure (RADIUS server) and facing this issue, then you can increase the Server time out on switch/WLC/AP and verify the result.
If you still face issues, then you can create a case with Pulse TAC to review additional logs.
I'm facing error with message:-
Authentication Rejected By Server Error: 1308
OS:- Windows 10 Pro Build Verson 1903
Please suggest a best solution.
