tell me please, what could be the matter?

Answer 1

proto tcp-server
try just tcp
and check if the port is open and if openvpn is listening on it

Answer 2

First, in the client config, you have the remote parameter configured incorrectly. You must specify the ip-address of the server interface that will be used to connect to the openvpn server. And the address from the 10.10.10.0/24 subnet will be issued to your tun interface.
Second, try switching to udp. For a tunnel, you won't notice the difference, packet loss is still controlled, but increase the performance of the tunnel.
