 * I am wanting to use ewww to optimise my jpg files, but i keep getting a timeout
   error. I have modified the location of the wordpress upload folder to be on a
   subdomain and not in the wp-contect folder to increase page loading times. I 
   am assuming this is whats causing the error. Is there a way to fix this?

 * That is unlikely to be the cause of a 504 error. That usually means your site
   is behind a proxy/CDN, and the proxy gave up on the response from your server.
   Try turning off parallel optimization and see if that changes anything.
