Dnsthingy block marketplace

Today I try new customer , Bronze trial version and Dnsthingy , when I install Dnsthingy the marketplace is blocked , yum update from line console is blocked to , the server access by webconfig is slow , in the server console I try ping google.com it resolve to 10.0.0.2 ( is secondary Dnsthing box ) , I've done many dnsthing and gateway management installations and this has never happened to me, I was noticing that a version was released on July 28, I suspect a bug or issue , the app version is 1.4.3.

When I disable Dnsthing , server normally works .

Thanks for you help
