KB5031361 on Windows Server 2019 cause the RAS L2TP VPN not work

[AshleyKwan]

Hi,

After I installed KB5031361 on my Windows Server 2019 what installed RAS and enabled L2TP VPN. I cannot connect to the VPN on my Android and Windows device. I checked the log and no error in the log file and it is normal shown on MMC. I must restory my server from backup to resume.

Is there special client version for this updates?

I have the same issue but with a VPN client not authenticating against A/D. Have you made any progress? I opened a case with MS Support 2 weeks ago. I have received no response. Thx.
