this is my first post here, hope I made correct formating
I've set up an openvpn server on an openVZ VPS. struggling for 2 days but connection always failed by:
TLS Error: TLS key negotiation failed to occur within 60 seconds TLS Error: TLS handshake failed
firewalls (iptables on server flushed, win firewall disabled) both sides has valid IPs and there should be nothing blocking traffic in between.
all the possible solutions I tried but with no luck: -I installed a vm locally, setup the openvpn server and client,created server and client keys and configuration files, connected successfully. then transferred configurations and keys to the VPS and client, change IP settings. still the TLS error
-I tried reversing the connection, set up the openVPN server on my client machine, and client on the server machine. still the same error message.
tried to higher the log level to 6 and this is the logs:

I think it would be a kind of network problem, MTU related. how can I identify where is the error I'm really frustrated, any suggestion please?
