After opening it up, check to see if the “bitstudio.com” service or app is blocked. If it is, try to enable it to work normally. This has been seen conventionally in the “Breezeline” internet service and also some others. Otherwise, you can go to your router’s security page and check over there.

Instructions to open your router’s security page differ depending on the internet provider that you are using. And, they should be available on their website or through their helpline.

Solution 4: Verify Server Outage
