For some reason every time i try to join a Minecraft server it says that it is down for maintenance. This is the whole reason i got Minecraft for PC is to play bed wars but it was a waste of $30 i even waited a while to see if it really was down for maintenance but no it did not work it has been 2 months since i first got it and i am mad i just need some help for this problem and my brother is having the same problem i tried deleting and re downloading it but it did not work i tried downloading java to my computer but that also did not work.
