Wvd FXlogix Profile taking Longer time to load

Jaganljpmail 1

We have a WVD Host pool with 3 WVD Hosts When user to login to the pool it takes longer to load the profile and gets stuck at "please wait for FSlogix App Services"

When I set a filter on User profile Service in Event viewer I See Event IDs 1534 and 1542 around the time when a user tries to Login to their WVD.

If this is a known Issue please let me know a resolution. Only recent thing did was update fxlogix agent and update windows patches.

Thanks,

Please check the fslogix logs from the machine where you see the login delay. Here is the log file path:- c:\Program Data\Fslogix\Logs\Profile
