Asp.net – Angular and request IPs

Good night.

I’m currently developing an app with Angular15 as frontend and an ASP.NET API as backend. Both are deployed in IIS v8.5 servers.

Recently, I have found that when my companions enter the app to do some tests, the REST requests that are sent to the backend are being done with my companions IP instead of doing it with the server IP where the frontend is deployed.

This is causing some troubles so I want to know if there is a way to make the Angular frontend do all the requests with the server IP instead of doing it with the client IP.

Thank you!

This is the way I’m doing the REST calls:

In .ts:

this.persistenceService.save(this.info).subscribe(
      data => {
        console.log(data);
      });

In persistenceService:

save(info: CustomObject): Observable<any> {
return this.http.post('https://backend.com', info, {headers: {'Content-Type': 'application/json'}});
}
