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:
