incredibly laggy

since yesterday everything has been so laggy, it doesnt matter if its a modpack or not, and i also already created multiple servers, nothing changed. my wifi is incredibly fast and my connection is just fine, also ive been using aternos for months now and this has never happened before, which leads me to think its an aternos issue and not something related to me. my friends are also laggy, which just proves the whole point, i dont know if you guys are aware of it already but im just reforcing it

edit: other errors are also happening, and most of the time i just get disconnected from the server.
