I try joining server "Disconnected: purplewasfun Timed out"

I was playing in my favorite Darkrp server yesterday and it usually says in the bottom right it usually says downloading something, then i’m in the server but now it says “Getting addon #1124553234” Thoes numbers keep on changing and then after about 10 minutes it says “Disconnected: purplewasfun Timed Out”
It also says this for a lot of servers but not all.
Please help someone

If it only happens on certain servers, then it’s probably because you have bad internet. What is your down/up speed?
