OpenVPN + OTP - TLS Error: local/remote TLS keys are out of sync

[mliebherr]

Hello,

after adding OTP to our OpenVPN Server we get errors like:
  TLS Error: local/remote TLS keys are out of sync

and the VPN Stopps/Disconnects after 1h. This happens just for a few but not all users.
I already checked the Time on the OPNSense and Client system.  I also set "reneg-sec 0" on the Server.

Any other ideas why OTP would cause this problem?

Cheers,
Mario

Did you get anything figured out with this? We recently switched over to OpnSense with the OTP as well. We have been getting people set up on it this week and started experience this issue with the TLS keys out of sync.
