"Pinging..." issue in 1.7.2

Hello everyone,
This is probably a very easily solved stupid problem, but I cannot seem to find the answer anywhere. I use "NO-IP DUC" and I have for quite some time. For 1.7.2 we decided to fully redo the world to start and fresh, and prior to that everything worked fine. Now, after doing everything set up, I can no longer have people connect.
-Yes, the ports are open.
-Yes, the Ip address is left empty in the settings.
-Yes, my firewalls are down.
-No, I do not have a virus protection to block it
-Yes, I have plenty of memory to allocate to the server.
I have covered all my bases and am near banging my head against a wall....please help!
Thank you!

 

You mentioned other couldn't connect but can you personally connect?

I can connect using localhost, but it is very laggy and glitchy

Try using the latest Development Craftbukkit Build, and see if there are any updated plugins.

Try reportforwarding, that seemed to help for me.

 

not currently using any plugins, sense we just redid the server from scratch.

did the re-portforward, still having the same issue.

ok, i figured it out. for some reason my no-ip duc was out of date when it wasn't before. As soon as i updated it, everything starting working perfectly. Thank you so much for all of your help!
