I am also trying to mirror GameFAQs this week... same exact problem! -_-

Be sure to have Max speed: 247000  (1 connection per second max) or they will
stop the mirror. 

I also cannot seem to figure out why we keep getting the Error:  "Bad Request"
(400) at link <https://gamefaqs.gamespot.com/> (from primary/primary)

No data seems to have been transferred during this session! : restoring
previous one!

The mirror always come up BLANK.... odd...
