Unable to connect Open VPNServer with TOTP

[anupam.dutta@314ecorp.com]

Hi,

I have configured open VPN server in OPNSense.But, when we are going to connect VPN server through TOTP server I am getting error "The username and password were not accepted by the remote VPN server." When I am going to login with local password, it is working fine. I have previously configure other two VPN server in OPNSense on my two different setup, those are working fine. Below are details.

OPNsense 23.1.10_1-amd64
LAN Network: 192.168.0.0/16
Tunnel Network: 10.10.13.0/24
WAN IP: 103.71.X.X.

Also strange thing it was working 1week before. I have reconfigured setup several times from scratch through this URL https://docs.opnsense.org/manual/how-tos/sslvpn_client.html.But, no luck. I don't find any clue.

Any one please help.

Thank you in advance.
