I cant use multiplayer on Minecraft

I am using an Ipad, and it started happening on the la test update (nether) its up to date, I can play normaly on single player but im unable to join realms, servers or my friend's worlds, Ive checked my settings and both clubs and multiplayer are enabled,
even though thats the problem Minecraft tells me there is.

I will mentón that everything is enabled on the tab that most threads tell you to check.
