I am once again asking for your financial support

i have this error Internal Exception Java io . IOException forcibly closed by remote host. i have this bug in realms. most of the time when i join the realm, nothing works, mobs nor players move and i cant interact with buttons, doors etc. my friend says that im not moving when this happens. every mob still moves around me and i cant move so i also get killed because of this. when when i get this error, i leave but i actually leave 15 seconds after i left. i have a stable wireless  internet (20ping and 33mbps) and i still keep disconnecting. it sometimes works fine but usually i cant even play. it also sometimes occurs when i travel to end or the nether.

I have tried:

-Reconnecting to internet

-Switching internet

-Enabled the operating systems restricted environment

-Ticked private on Java(TM) Platform SE Binary

-Connecting without any mods (I am using optifine)
