I have openvpn server hosted on Brume2. Been getting this error trying to connect from GL-inet routers (Slate AX, Puli) etc. Not getting the error when connecting from Iphone/Android using openvpn app.

TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)

After waiting several minutes, it did manage to “connect”, but doesn’t display any data flowing through.
