I'm having this issue for 2 days but my friends can connect to my server or other aternos servers.World loads(my player data such as my inventroy,xp loads as well) for a moment then no other ticks are loaded everything freezes in time and I get kicked 15-20 seconds after entering the worlds.Error message can be just "Disconnected" or "Internal Exception: java.io.IOException: An existing connection was forcibly closed by the remote host.".I searched for a way to solve this problem I couldn't solve it then I'm here asking for help.Log: https://mclo.gs/ycCcXlS
I guess your answer will be, this is about your internet connection try to restart or get better internet it.I've already done it by myself and tried another solution, changed wireless connection to wired.Called my internet service for checking things and they say everything is normal.
Edit: I also tried dynamic IP and flushed my DNS
