Keep disconnecting but my internet isn't going down?

I have no idea why it keeps disconnecting me from every server I join, the minute I lose connection I try to load a website and it loads perfectly fine. Please help!

Check firewalls, and Anti-virus

Make sure to set Rust is in a trusted setting or whatever makes the connection go through.
