I have openVPN running on a Synology NAS using TCP 443 to overcome blocked ports at work.
Using cellular data, I am able to connect to it just fine. But when behind corporate firewall, I get the NETWORK_RECV_ERROR message and it does not connect.

I actually use to connect via L2TP/IPSec just fine, but it seems they started blocking that so I wanted to give openvpn a try with port 443, knowing that is open and working. As I have port-sharing enabled, I can properly view web pages behind the firewall.
TIA
