Problem connecting to server

Hello,
I found Aternos today and I'm running into troubles connecting to my server. I tried it with Vanilla and it worked great. I then tried making a server for The 1.7.10 modpack. I opened and watched the console as it ran everything and it and it doesn't look like anything went wrong, but I attached the log just in case. The server opens fine for me, but when I try to connect minecraft tells me that it can't connect and I need to try restarting my game. I restarted the game and tried again but was met with the same message. I've done this twice and received the same result both times. I've made sure I have modpack installed on my computer, and I'm not sure what else to do.

I am using the correct modpack on both. Technic the 1.7.10 pack 0.9.4. I was able to connect now, but the server doesn't stay open for very long. I made sure the number of players on the server matches with the number allowed. I watched it on the Aternos website and there's no countdown for the server to close and it just stops after being on for about 2 minutes.
