Can't connect to the server I run

I've been unable to connect to my own server for about four days. I can connect to any other server not on Aternos, but whenever I try on Aternos I time out. I can open my server console, I can VIEW the server, but I can't join it. I've tried the DynIP, and it didn't even let me hit join in minecraft. The join button stayed grayed out. Please help, I'm frankly very annoyed. For more help, other players CAN join my server, just not me. I've logged in and out of my Mojang account, I've cleared my DNS cache, I've restarted and then CHANGED WIFI networks. I cannot figure out what is the problem

correct. I use the original Minecraft Launcher, tried the dynip, reset and then changed dns, I even shut my firewall completely off for a couple minutes to see if it was an outbound connection error. nothing worked.
