Sorry for the delay in getting back to you.
We already have a fix for this bug that is queued for being sent to net.

You can find it here:

https://github.com/OpenVPN/ovpn-net-next/commit/beb427921aafd186eb139349bf04c6d54a4927f5

I was caught by Sashiko's fire and therefore had hard time sending all the fixes in my queue, but I am getting there.

If you want, please check the patch at the link above.


Thanks a lot.

Best Regards,
