Minecraft Realms Connection Issue

Sorry if i posted this here and no one could help me with this but the problem is that i keep getting disconnected from realms but not from multiplayer servers, every time i log in a realm it lags me out where i would get that in the screenshot, or either Timeout or Disconnected due to a connection lost. I've tried to reset my modem multiple times, including restarting my laptop and nothing seemed to fix it. So if anyone could help me resolve this problem, i would be glad. Thank you and have a nice day!
