Sorry i didn't explain better after i login with ip and i change all my mining pool, worker infromation. I saved it, then i went to mining status and the web browser keeps timing out. It says something like, " oops it tok to much time" that might not be the exact words.
Can you still ping it? Maybe it dropped off your local network for some reason and got assigned a new IP address. Also, as silly as it sounds, have you tried restarting your miner and / or router?
