I'm getting kicked by my realm every time I try to get in

Hi, me and my friend have a realm for playing together, but there is one issue that affect me and not him, so I believe it's just a problem of mine. When I try to log in into the realm, the game seems to freeze, and it's unable to load most of the blocks, buildings and chunks around me. After a little time, I get kicked by realm and the with this message on the screen: 'internal exception java.io.ioexception an existing connection was forcibly closed by the remote host'. I can't figure out what is the problem, I restarted Minecraft many times and this happens again, I hav tried to restart my decive but nothing happened, I also tried to change with my Wi-fi connection to the mobile phone's hotspot, but I can't solve this problem. Please help me, I can't even play in my favorite world that I have also payed this month, thank you
