Internal exception java.io.ioexception an existing connection was forcibly closed by the remote host

Sometimes when I try to connect to my server, or instead, ANY Aternos server, first the mobs load in, then the chunks, and then the inventory, after 2 seconds of loaded inventory, I get kicked off the server with the message "Internal exception java.io.ioexception an existing connection was forcibly closed by the remote host", I tried powering on/off my router, restarted the server, restarted minecraft, re-installed minecraft, re-installed java, but nothing worked.

Note: This does not occur all the time, it has a 50/100 chance to have this error.

Edit: Here's the log https://mclo.gs/uXFst1z

Connection forcibly closed by remote host

Yeah I checked it, even opened a ticket, how much time do you think it'll take for me to get a response, also, can I see or edit my request? Because I think I have traceroute the wrong thing.
