I can't connect my iPhone to my OpenVPN server

[myrrx]

I have set up an OpenVPN server on Ubuntu 20.04. According to the settings on the Internet , I created a file .ovpn, which I show below. The OpenVPN Connect application accepts the file, but when connecting it gives the error "PKey::parse_pem:error in private key:: error:0909006C:PEM routines:get_name:no start line". Please tell me what I did wrong.(I removed the personal data and trimmed the certificates.)
