SSL VPN Client not connecting Immediately after Installation

eFrancis 2 days ago

The SSL VPN client is not connecting immediately after installation and returns the error below

We have just uninstalled the previous version of SSL client and re-installed the above.

The last time a colleague installed a fresh OS on their machine, the SSL client initially failed to connect but successfully connected after an hour.

Our mobile team, responsible for enrolling people, is currently stuck because we just reinstalled the SSL client.

Any support. Thank you

Hi,

Thank you for reaching out to Sophos Community.

Based on the event logs, the User is having an issue with authentication.

Can you also check the Firewall logs?

Try to recheck the VPN configuration and Windows Firewalls, droppacket/packet capture.

For more reference, kindly see below

Do you have OTP enabled for the user? If yes - could that be a multi-second system time difference between client and firewall?

What I have always noticed is that the first connect using a .pro file where it loads the actual VPN profile results in an "authentication failed" when MFA is enabled. This could be avoided by Sophos.
