Hi,
I have a Sophos UTM virtual appliance running under ESXi 6 with a home licence.
I am trying to conigure OTP, so I enabled it and created a user with Portal access (SSL VPN and RDP over HTML5)
When I login to the portal, I see a QR Code, I scan it with the Sophos App for Android and it shows me the correct Username and internal Sophos name.
I then try to login again with username and Password+OTP and it shows me the QR Code again.
Back on the firewall, I can see that a OTP key was generated for the user.
When I click on the clock near the key and enter a passcode from my phone, most of the time it is telling me that the code does not exist or is too far off.
Sometimes it is telling me, that is far off but I could sync it. When I do this, it says syncing was successfull ,but entering the next code it is too far off again.
NTP is enabled and allowed for DMZ and LAN and the UTM gets the time from the default ntp pool.
The phone, of course, is ntp synced as well.
Any idea what I could do? I even reinstalled the UTM, no effect.
When I did it with a hardware appliance in my old job, it worked like a charm...
Best regards,
Matthias
