OPENVPN won’t reconnect after I switch configuration

Hi, I successfully connect to my OPENVPN config file on initial set up but when I want to switch locations I must use a different configuration file. When I switch to a different one my OPEN VPN won’t reconnect.

Please let me know any more information need to help me.

Thanks in advance.

Could you please share a config file that works, and one that does not work?
