file upload work localhost but doesn't work on server in asp.net core

Question

I can add localde when uploading files. But when I try it on the server, I get a 404 not found error. Normally, when redirecting url in my project, I do it as "url:" @ ViewBag.UrlPath / api / AddDocument / GetTechDocCode / ",".

While uploading the file, I used "url:" / DokumanEstablishment / Test ",".

Am I having an error while redirecting, what could be caused by this problem?
