So basically, long story short, I'm using Eaglercraft u50, and I try to log in, it boots me out. I use an 3rd party website and I've successfully done it before on an alt account. But when I restarted my PC, VelocityModeration seems to keep disconnecting me due to it not being able to verify my client (Mind you I'm using a 3rd party website that has the official version). Can someone explain why this happens and how to fix it? BTW, I'm on a school Chromebook that blocked the original website, maybe that's the issue?

If it can be fixed or mitigated, it will be appreciated.
