Error -1 is the "Absolute Zero" of errors. It means your computer can't find the Roblox servers at all. It's like trying to call a phone number that doesn't exist.

Is Roblox down when I see error -1?

Very likely. If your other websites work but Roblox gives Error -1, it usually means a major part of the Roblox infrastructure is offline.

How do I fix error -1?

First, check your own WiFi. If that's fine, try "flushing your DNS." This forces your computer to look up the fresh address for Roblox servers.

Why is the error number negative?

Negative error numbers in programming often mean a "critical system failure" where the app didn't even get far enough to receive a normal error code.
