Problem with OpenVPN iOS

Hi, I’ve problem with openvpn server on mikrotik. I can’t connect to the vpn from iOS.

Error:
Event: Transport_error Transport error on “my domain” NETWORK_EOF_ERROR [ERR]

I didn’t find any solution in the internet. Below my client conf:

client
dev tun
proto tcp
remote mydomain 1194
resolv-retry infinite
nobind
persist-key
persist-tun
#ca ca.crt
#cert user.crt
#key user.key
remote-cert-tls server
cipher AES-256-CBC
auth SHA1
auth-user-pass
redirect-gateway def1
verb 3

myca cert

pkcs12 pawel-vpn.p12

when I try connect to the vpn from iOS i see in log:

Any ideas?
Thanks

Problem solved/ I had to generate all cert again and convert it to pkcs12
