Latest C-SDK Version - Error creating BSD socket to be used for the websocket

We have a deployed Thingworx server on a Linode, running TW 6.0.3 with a certificate installed.

I've downloaded the latest C-SDK from the marketplace version 1-3-1-957 which also was supposed to solve the BSD bug:

https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS227278&lang=en&source=snippet

However, I still keep getting it. Any ideas on what is going on?. The Edge is a uClinux machine.

Gerard, is there a proxy server in place? Or are the connections going through a specific firewall? Would it be possible for you to check if they support websockets or not?

I'll have to check with the server admin.

I can connect to a  local TW server(without TLS) fine.

EMS is not a pre-requisite, correct?

If it works correctly with a local connection, but doesn't externally, we would need to check your network settings, mainly around firewall type or proxy involved. The BSD socket error is more or less generic, so we can't exactly pinpoint on where the issue could be, but checking the network settings would be a great starting point.

I didn't get your prerequisite point though - you can use either the EMS or the C SDK to connect.
