Hi there
Same thing happens to me in OMV 4.x.
TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
TLS Error: TLS handshake failed.
I am pretty sure it is a problem with the OMV pluging because I also have two other openvpn fully working, on a proliant with xpenology os an a Qnap, with no problems whatsoever when connecting from windows, android,linux, etc.
Any solutions please?
Thanks,
Regards.
