Cannot resolve host name

I am having an issue with TeamSpeak resolving the host name to my bookmarks. I am running version 3.0.18.1 65 Bit. I am running Win 7 64. Team speak was working on Saturday as I was logged in to our chat channel and talking with others. Yesterday when I tried to log in I started to get the "Cannot resolve host name" error. I check with other clan members and the address is correct. I can connect to the public channel.

I have tried the three below on my desk top and Android with the same error.
It worked Saturday as I was talking with Hawk.
I have uninstalled and reinstalled team speak twice.
