ProfileUnity Splash Screen Delay Due to IPv6 Timeout

Problem:

Users experience a prolonged splash screen (up to 7 minutes) during login. Diagnostic logs indicate a timeout during Azure AD group retrieval via GetUserGroupsAsync found in the client_Logon_[...] log

Symptoms:

• Splash screen visible for ~7 minutes
• Client logs show timeout in GetUserGroupsAsync and an exception: MsalServiceException with error code request_timeout
   

Resolution:

Note, there are two ways to remediate this issue. First covers the customers who can update ProfileUnity to a later version, and second option for customers that have to plan their upgrade later.

Remediation Options:
 

1. Upgrade to ProfileUnity 6.8.7 R2 HF2 (9309) at minimum but as Hotfixes are cumulative we suggest going to the latest HF available. This hotfix includes a resolution for Entra-related timeout issues.

Hotfix's can be found here ProfileUnity Hot Fix List – Liquidware Customer Support

Alternative workaround (for customers who can not immediately update):
 

2. Disable IPv6 to force communication over IPv4, which is more reliable in many enterprise environments.
