jsReport API POST request not work on Windows Server 2019

[Genhan]

Hello,

I deployed my jsReport application on Windows Server 2019, but its API endpoints are not functioning properly.

Here is the error:

Here is my sample request:

The jsReport studio is working:

Pinging API endpoint also returns correct response:

I successfully deployed the same jsReport application on both Windows 10 and Windows Server 2012, and it is operational on both OS platforms.

Any advice is greatly appreciated.

Thank you!

Are you able to render the reports from the studio?

What if you host the application on the root path localhost:3000 without using /reporting subpath? Does that work?

Are you able to make a request using some Postman tool? Maybe there is error in your client.

Is there some error in the jsreport logs?

Thank you for your suggestions, Jan. I discovered that the server might restrict external program's access to localhost. I will do more investigations.
