We have ASP.NET core web app hosted on Azure as App service. There is a file upload screen in this web application. On click of upload button, application tries to connect to a on-premise network file share drive and copies the uploaded file there. But after reading through few articles it seems that standard smb ports like 139, 445 are blocked to access from App service. I guess which is why we are receiving access denied while doing file upload.
Any suggestions on how can I access the on-premise network drive for above requirement?
