  • Just to confirm, how exactly have you hosted the app?  When you create a Cloud Service, Azure assigns it to a subdomain of Whereas Azure WebApps, assigns a subdomain of Could you confirm if you have hosted your app on Azure Cloud Service or Azure WebApps? Or have you hosted your app on an Azure VM?


    If this is on Azure App Service WebApps; just to highlight, all Azure Web Apps run in a secure environment called a sandbox. Each app runs inside its own sandbox, isolating its execution from other instances on the same machine as well as providing an additional degree of security and privacy which would otherwise not be available.


    As mentioned in this document - The following PDF generators are supported:

    • SQL Reporting framework: requires the site to run in Basic or higher (note that this currently does not work in Functions apps in Consumptions mode)
    • EVOPDF: See for vendor solution
    • Telerik reporting: requires the site to run in Basic or higher.
    • Rotativa / wkhtmltopdf: requires the site to run in Basic or higher.
    • NReco PdfGenerator (wkhtmltopdf): requires subscription plan Basic or higher.

  • To understand the issue better and for providing better guidance on your scenario/issue, I would like to know the following:

    Have you deployed a database server on an Azure VM? Could you provide more details on your database server? How exactly did you migrate it to Azure? Kindly do share any documentation that you referred to for the process and also share a screenshot of the issue after concealing private details.
