OVPN Client setup for vpngate.net

Hello, I just wanted to try their vpn services and have a problem with certificates embedded into ovpn file.
I can extract them (since they’re in base64 pem format) but can’t find a way to convert to compatible format.
If you’re interested, I attached one of ovpn files

in my experiments, I found that ‘openssl rsa’ command understands this client certificate, but simply copying certificate and key into .pem file does not work - router does not want to import this file

I read your article here. It’s not the problem which you think complex. I have had the same issue & I got an easy solution here http://www.ipadvpn.net. This might help you a lot because I did it.

Not very clever to post your personal certificate on a public forum!
I would advise you to find how you can cancel this certficate and generate a new one, or when that is not possible
cancel your VPN account.

It’s free VPN service, and I the client certificate is ‘pubic’ - same for everyone. At least I did not register anywhere at their site and .ovpn files are public
It’s an educational project I think. I searched for a japanese proxy/vpn so I bumped into their site and decided to try it
