@arethiya Must have overlooked your post until now. Tried to connect to the site with your script and notice that the was a quotation mark missing in the Source step. Added on in the Coockie section like so:

Cookie="F859B23EBA8.......

Then the "token" error disappeared, but the site didn't accept the connection and timed-out. Perhaps you can fix that yourself.
