OpenVPN configuration help, android and tunnelblick

[jfowles]

Hey all,

Been troubleshooting an issue for a while that I just can't resolve.
I have OpenVPN running on my SG-3100. Using my Android phone I can connect just fine, but using a Mac with Tunnelblick, it errors out at the TLS handshake.

However, the connection for my Mac will work if I am using my phone as a hotspot. So I know that the issue is not with the configuration options on the client side, or at least I don't think it is any issue with tunnelblick vs android support.

I have allowed multiple connections from same CN and 10 concurrent connections.

Obviously it is something to do with the handshake since my phone works and can "proxy" VPN connections, just not sure what is going on...

Current config is:
dev tun
persist-tun
persist-key
cipher AES-256-CBC
ncp-ciphers AES-128-GCM
auth SHA256
tls-client
client
resolv-retry infinite
remote www.*****.com 443 tcp-client
setenv opt block-outside-dns
verify-x509-name "****" name
remote-cert-tls server
