Fiddler everywhere request rule error

Hi there,
Few days ago I got fiddler everywhere subscription, I needed it in order to change my proxy to my localhost. This rule was working for 1 day, and now it has stopped working and I am also experiencing that even when fiddler is not running I can't even access the url itself. 

First image is related to the request that I need to do, when the url contains XXX I need to change the host to my localhost, as I said above, this was working okay for 1 day.

Thanks in advance
