Provider Hosted App not visible in SharePoint after uploading to app catalog

I have created Provider Hosted App and deployed to Azure webapp. Packaged the app and uploaded to SharePoint online app catalog.
But when i am trying to look for the app in "Add new App" the app is not visible to add.
I have no clue where to look for to troubleshoot. Please give me some idea where to look at exactly.

Few details:

  1. When browsing the Azure webapp directly through browser, it gives Something went wrong error.
  2. When uploading the app to app catalog in SharePoint online, it didnt give any pop up to deploy or anything. It just got uploaded. Also i don’t see any deploy error in the column.

Thanks in advance,
Usha.
