No put in minecraft servers will work

Last night I was playing factions on minecraft pocket edition, but today was a different story. I tried to get on to fallentech.io but it tells me there is 150/-1648392047 players on and the number just keeps changing. I tried deleted minecraft and getting on different servers and none of them will load into the server. When I would click on mine plex or lifeboat it will work so I'm stuck at a crossroad. What do I do?
