LCIT

Hello I'm experiencing difficulties to connect to my SSL VPN (USG210).

(I replaced what I believe to be sensitive data with "******")

I tried everything (ports opening in firewall, disable windows defender, DISM and SFC repairs, reset network settings, test with another network card, internet box and computer resets, etc).

Whatever I try I keep getting these "Can't get authentication token(1)" and "ia is null" errors.

Any help appreciated thank you.

Hi @LCIT, and @bYAdmin
Welcome to Zyxel Community.
Is the SSL VPN connection issue only on specific client ? Assume it is general to all windows client.
Please send  my your configuration file in PM for further checking.
