OpenVPN not working after upgrade to RouterOS 7.1.3

RouterOS General
1

Hello,

I have a problem with Open VPN. It stopped working after I do an upgrade from 6.49.2 to 7.1.3.
The certificates and settings are the same as on previous version, so I switched to TCP in OVPN server settings.
An connection is made from Ubuntu OS with username/password authentication only. It worked well with version 6.49.2 of Mikrotik.

In debug I have:

connection established from xx.xx.x.xx, port: 59009
ovpn: connection established from xx.xx.x.xx, port: 59009
ovpn: sent P_CONTROL_HARD_RESET_SERVER_V2 kid=0 sid=e45e256eae7cd693 pid=0 DATA len=0
ovpn: <xx.xx.x.xx>: disconnected <TLS failed>

I tried everything on Ubuntu but it simply won’t work.
Does anyone have some similar problem with OpenVPN on new version of RouterOS 7 release? Can you help?

I have the same problem you described, everything was working fine until I upgraded the system.
I would appreciate any suggestions.
Many thanks.

You maybe want to update to after 7.11 version where the issue with certificates with SHA512 was solved.

*) certificate - restored RSA with SHA512 support;
