This is Windows 11 box and all Windows 10 machine don't have issues connecting.
I have tried removing all Watchguard and Fireware certicates and
loading from http://:4126/certportal

certificate loads fine and says status is OK, no error viewing the certificate.
It is loaded into Trusted Root Certificate Authorities

but after it loaded and connection keep failing.

recently migrated from M270 box to M-T85, this is Win 11 stop connecting to new cert of the M-T85

Any suggestions?

  • I created a CASE with Watchguard tech support.

    the fix was to delete all files in C:\Users\%Username%\AppData\Roaming\WatchGuard\Mobile VPN and then try to connect to the SSLVPN.

    It worked and finally connected.
