About the Year 2038 problem in the OpenVPN Client

Post by gog » Thu Jun 30, 2022 12:33 am


I would like to ask about the Year 2038 problem in the OpenVPN Client.
I am trying to create original VPN software with openvpn-2.5.3 source code.

I installed a client certificate that is valid for 25 years.
After that, I have set my Windows client and Linux server date are 19.Jan 2038, then my OpenVPN client failed to start with the following error.

Is the OpenVPN Client still not addressing the Year 2038 problem?

Year 2038 problem

Error message on the dialog:
openvpn.exe- Application Error
The instruction at 0x0000000000464A0B referenced memory at
0x0000000000000000. The memory could no be read.
Click on OK to terminate the problem

Error message on the OpenVPN client log:
IService>OpenVPN exited with error: exit code = 3221225477
IService>Check the log file for details

Kind Regards,
