I have configured app domain and able to ping also . I have configured the app management and subscription setting service applications . I have configured the App Catalog URL also .
After deploying the sharepoint app in to the app catalog site , I am facing the below issue.
The host name resolution (DNS lookup) for this host name ( ) has failed. The Internet address may be misspelled or obsolete, the host ( ) may be temporarily unavailable, or the DNS server may be unresponsive.
Please check the spelling of the Internet address entered. If it is correct, try this request later.
Please help to solve this issue
