asp.net core 2.1 and Error 502.3 - Bad Gateway



  • Hello
    I am trying to use jsreport nuget packages in my asp.net core 2.1 web app, essentially copying the methods used in the sample WebApp provided. On the first run of my app all works, subsequent runs (via Ctrl-F5) inevitably produce 502.3 Bad Gateway error on start of my app. IIS trace logs below:
    ModuleName
    AspNetCoreModule
    Notification
    EXECUTE_REQUEST_HANDLER
    HttpStatus
    502
    HttpReason
    Bad Gateway
    HttpSubStatus
    3
    ErrorCode
    2147954429 this seems to be ERROR_WINHTTP_CANNOT_CONNECT

    I am running on my local machine against local IISExpress
    Any help will be appreciated
    Thanks
    Rumen



  • This is not the jsreport error.
    Try to add some try/catch and get the actual error.
