@ tednelly
You appear to have modified your settings as the HTTP port(s) has many more options.
@ LadyJ91
These are the ports listed in mine 80,8080,8091,8081,8008,8888,3124,3127,3128 if the port you use for the Web Accelerator isn't listed, then add it to the end. You must place a comma between entries, no space required as in my list above.
Do you have the proxy port set manually into your browser ?
