Multiplayer errors

Ok so recently i joined a server called bordercraft, it is a fun server and one day te admin gave me and my friend 1 stack of bedrock and 5 blaze eggs from creative mode. so one day i had to prove a point and show some little kid that i have this stuff. when i tryed to place my egg it disconnected me.. now whenever i try to get into the server i ethier have the "cant resolbe host name" or "communication error" and the "cant reach server". i dont know if minecraft-server-list.com is lying to me but its saying the last online ping esd 10 minutes ago even though this happened last night, it also says thr server is online. Now some people are going to say "just go look at other threads" but i dont want to i want someone to tell me how to fix this server on THIS post... Also another thing to put in my other servers work fine..
