If this happens, you need to rename them to 'private-ca-itp.crt' and 'all-via-itp.ovpn'. With standard configuration Windows 10 does not show the endings of the file names. The endings are correct if for 'all-via-itp.ovpn' the file type is shown as 'OpenVPN Config' and  for 'private-ca-itp.crt' as 'Sicherheitszertifikat' or 'security certificate'.
