"Unable to retrieve patch data. Please check network connection. (311)" error
I got this error when attempting to patch and download 6.1.3. I am running SWTOR through Steam and had no issues with the initial download (so happy to try things involving firewall/DNS/etc., but I don't expect anything to have changed since then).
While clicking buttons to try to figure things out, I verified the game files in Steam, which proceeded to delete my entire game... so now I can't connect to the patch server, AND I need to re-download everything!
My logs say the following:

Before I accidentally deleted my game files, I was getting the same error with a different file from http://cdn-patch.swtor.com/patch, probably because I was only trying to download 6.1.3. Any tips from folks? I've already tried multiple times hours apart, restarting Steam, restarting computer, etc.

The fix ended up being my hosts file (roughly described in the link to https://support.microsoft.com/en-us/help/972034/how-to-reset-the-hosts-file-back-to-the-default on http://www.swtor.com/community/showthread.php?t=669611&page=2).
My guess is that once upon a time, SWTOR required updating the hosts file to map cdn-patch.swtor.com to 64.145.87.64, and the IP is just no longer valid. In any case, frustrating but problem solved.
Amazing answer, I searched everywhere, must be especially the case for us long time players as this had snuck in at some point. Thank you!
Glad you found it helpful! :)
