OpenVPN configuration error General

I tried to configuration OpenVPN TLS and I got an error message “Failed to start OpenVPN tunnel”. Every time i got this message when i try to configure. Can anyone suggest me what is the actual issue?

I don’t know, but I found this old thread that might have some clues? Let me know if it helps.

Thank You Ken!
I hope this thread will have a proper solution. But after that if I have still error then I will contact you again.

Hi, Ken

Thank you to suggest me the right path. Now the error is resolve and properly connect but in the meantime I google how to connect open vpn automatically. Most of the result were about VPN and they also offers openvpn connection. Do you think they are reliable?

These are vpn sites that offer openvpn

Do you think they are reliable and secure?
