Something not specific to Tableau.
Seems related to your web server:

Hi Matheus, that IP address(18.104.22.168) looks like a Microsoft address in Washington DC (http://www.ip-tracker.org/locator/ip-lookup.php?ip=22.214.171.124). Are you sure you're publishing to localhost? If you're already signed on to the server, try signing off, and when you sign on again, make sure you've specified the proper host.
Thank you all.
I resolved the problem using the local ip.
