Hi  Sushil,
According to your description, my understanding is that the add new document link was not working on machine where Office web apps set up with this SharePoint server after you upgraded SharePoint team sites
from 2010 to 2013.
For your issue, it can be caused by integrating Office Web Apps with upgraded SharePoint Site.
Firstly please make sure claims-based authentication is used by the SharePoint web application that is used to create the new document. Only web applications that use claims-based authentication can open
files in Office Web Apps. To determine the authentication provider for a web application, follow these steps:
1.In SharePoint 2013 Central Administration, click Manage web applications.
2.Select the web application that you want to check, and click Authentication Providers on the ribbon.
The authentication provider must be displayed as Claims Based Authentication for Office Web Apps to work correctly with the web application. To resolve this issue, you can delete the web application and recreate
it using claims-based authentication, or you can change the authentication method of the web application.
Secondly, make sure the WOPI zones match on the SharePoint 2013 and the Office Web Apps Server farm.
To do this, run the following command on the SharePoint Server:
Get-SPWopiZone
The result will be one of the following:.
internal-https
internal-http
external-https
external-http
Next, run the following command on the SharePoint Server.
Get-SPWOPIBinding
In the output, look for WopiZone: zone. If the results from Get-SPWopiZone don’t match the zone that is returned by Get-SPWOPIBinding, run the Set-SPWOPIZone -Zone cmdlet on the SharePoint Server to change
the WOPI zone to match the result from Get-SPWOPIBinding.
If not work, you can try to disconnect SharePoint 2013 from Office Web Apps Server and re-configure Office Web Apps for SharePoint 2013.
