I wish I could, but with this issue, I cannot share any images or resources due to NDA.

I have a .net core 6 API hosted on AWS(APP 1). No certificate, no https ability, and is load balanced.

I can call the API on AWS from my local device and reach it successfully. in HTTP mode.

If I call the API from the browser of the VM where the IIS server is running, I get a 503 error after it forcefully redirects to https.

I was provided some IP to update the Proxy of the VM, and can finally reach the application from the browser of the VM. when I now call the API on was from the VM’s browser, I can reach it successfully. it does not redirect to https.

I have a .net framework project hosted on the VM’s IIS. I have tried to call the API on AWS(APP 1) through the .net framework application(APP 2).

I am getting 503 like I did in the browser. Please can you speculate what the error is? or how i can solve it?
