👉 Access denied when trying to access the service

Hello Netlify Support,

We are experiencing ongoing issues with a web application hosted on Netlify:
imc-permits-portal.netlify.app

Issue description:

  • Intermittent login failures
  • Non-responsive buttons and UI sections
  • Forms not working during permit application process

Investigation:

We checked network requests and found that the backend API:

https://imc1-server.herokuapp.com/api/login

is returning Content-Type: text/html instead of application/json, which suggests:

  • possible backend misconfiguration, or
  • backend service instability / fallback HTML response

Impact:

This issue is affecting daily operations and users cannot reliably complete permit applications.

Request:

Could you please confirm if there are any:

  • Netlify routing / proxy / redirects misconfigurations
  • Known issues affecting API calls from hosted frontend
  • CORS / edge behavior that could cause this response type change

We are trying to determine whether the issue is on Netlify configuration side or backend service side.

Thank you.
