ERR_CONNECTION_TIMED_OUT .. can't open Blockstack.. help

I downloaded the Blockstack Browser, and when I try to open ERR_CONNECTION_TIMED_OUT comes out. (localhost8888).

Is this something I can solve? I had been able to open Blockstack 3 days ago…

Please help! I want to register!

Hey @pepe9174, sorry to hear you’re having trouble! Can you try http://localhost:8888? Note the : between localhost and 8888. Thanks!
