No connection to ExpressVPN via OpenVPN

    I'd guess the add-on is checking for keysize even though it's a long deprecated option. You should flag the problem to the add-on maintainer through their GitHub issues list. The add-on is not managed by LE project staff.

    Are you absloutely sure your using latest ovpn files from ExpressVPN, I would download the very latest and double check contents.

    I compared your ovpn content with one of my current ovpn's with OpenVPN working fine for me. You seem to be missing a second certificate at the very bottom of the file?

    Thanks chewitt. I already asked this on github as well. but:

    problem solved.

    go to settings and chose "user specified" when asked for a vpn service. (not ExpressVPN)
    enter your credentials and keys.
    start the vpn and you will receive an error log prompting you to make slight changes in the .ovpn-file:
    delete "ns-cert-type server" and add "remote-cert-tls server" instead.

    That solved the prob for me
