Data connection

Hi All, 

After database server ip name and hostname change we are getting below message on data connection:

Ensure that your Qlik environment can access the database server and update the settings for data connection.

I have tested ping cmd and its connecting. where I can update my  data connection setting because I have edited the connected in editor as well as qmc there is not option to update IP address or hostname...
