When I play ANY minecraft server my game can not load the chunks over around 10 when I have the game set on 24 chunks( I dont think it is the server bc my friends run the server fine ) , and in singleplayer my game has no problem loading the chunks.

A week ago my minecraft had no problem running chunks on servers but today my minecraft can not load more than 10 chunks on every server I play, but in singleplayer my computer can run the game just fine. please help.
