Trouble in loading data from local Orthanc server

I want to get the data from my local Orthanc server but getting a proxy error:

My default.js file looks like this:

I am using Nginx to proxy-pass the Orthanc-server:

When I am going to this url http://localhost/orthanc/dicom-web/studies I am able to see an array object of studies.
