I'm encountering an SSL certificate issue with Angular SSR (Server-Side Rendering) when trying to access my .NET backend. The interesting part is that everything works perfectly fine on client-side rendering.

Environment

  • Angular 18 (also tested with Angular 19 RC)
  • .NET backend running on https://localhost:7205
  • Certificate is added to root certificate store and shows as trusted in browser

What's Working

  • Client-side requests work perfectly fine
  • Certificate is recognized as trusted in browser
  • Backend endpoints are accessible directly through browser

What's Not Working

During SSR, I get the following error when trying to make HTTP requests:

HTTP Error Intercepted: HttpErrorResponse {
      status: 0,
      statusText: 'Unknown Error',
      url: 'https://localhost:7205/api/Account/MyInfo',
      ok: false,
      message: 'Http failure response for https://localhost:7205/api/Account/MyInfo: 0 Unknown Error'
    }

I attempted to disable SSL verification on the server by adding this to server.ts: Beside that, the file is the default.

process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';

However, this didn't resolve the issue.

Any guidance or suggestions would be greatly appreciated. Thank you!

  • setting env that way is not a working way. you should set it as env variable before starting the process Commented Nov 15, 2024 at 10:23
  • @Andrei This is my hole npm start script "cross-env NODE_TLS_REJECT_UNAUTHORIZED=0 ng serve -c development --ssl --ssl-cert ./ssl/server.crt --ssl-key ./ssl/server.key" Sadly still the same error Commented Nov 15, 2024 at 12:18
