WebIDE (Local) keep asking Authetication Required

Hello,

I have installed WebIDE locally and created a destination with my backend Gateway system. Now when I try to browse the catalog in WebIDE it keeps asking my credentials. I tried multiple times but this popup is not going away (not giving any error as well)

I checked in console and found it was trying to make a call to below URL

http://localhost:8080/webidedispatcher/destinations/SID /sap/opu/odata/IWFND/CATALOGSERVICE;v=2/ServiceCollection?$format=json

So, I tried this in POSTMAN (REST client) and there it is giving me a successful response. But not working in any browser (there it keeps annoying me with authentication pop up)

Can someone please help me in what wrong I am doing?

Appreciate your help in advance!
