When I was today installing openvpn once I had everything configured, I got these errors.
On the server side.
Connection refused (code=111)
and on the client side.
TLS Error: Unroutable control packet received
After googling for a while I found the solution, all have to be with the time in both sides (server and client) so the solution is.
and then sync the clocks on both pcs.
