Unable to establish open VPN connection

i configured an open VPN server on my USA home network using a GL Inet router and downloaded the config file then upload it to my other GL from a different country. The USA server is running fine but the configuration file refused to set up on my client router form the other country. every time i run the filed then the VPN from the client router is down and i lost connection.

Please kindly advise what was missing on the configuration

If you are using the same config file on both sides then one of them is wrong. One has to be the VPN Server and the other (usually the remote) must be the VPN Client.
