Multiple Errors When Joining Server

Every time I connect to my server, different errors show up each time. I get "Timed Out", then the "connection was forcibly closed by remote host", then "Disconnected". They're not specifically in that order, but those are the errors I get each time I try to connect to my server. I use TLauncher and I have the "Cracked" option turned on. I tried turning all my firewalls off completely (which is a bad idea but I wanted to see if anything helped). The Jave SE binary has always been allowed through the firewall (with the private and public boxes ticked). I tried connecting to different servers that were not from Aternos and they all worked. My server is not new, I've been using it for a long time and plenty of people have joined it before. Hope someone knows the fix to this.
