Can't play anywhere but spawn?

[ChickenMonkey]

I'm almost positive this issue is on my side but; I've finally fixed my computer's problem with not being able to connect to the internet and everything works fine now. The reason i'm posting this on here is because whenever i'm on the server the only place I can stay online is at spawn. The second I go to my base or anywhere in the wild, I usually disconnect within about 2-5 seconds. I just think it's weird because I can use the internet and join different servers just fine.. I've tried a couple different things to fix it but I don't really know what to do anymore.
