Problem with Health Check code 500

To resolve this:

1. Configure CORS on your backend:
   • Set the Access-Control-Allow-Origin header to include the domain of your frontend. You can use * as a wildcard to allow all domains, but be cautious with this approach.
   • Also, set Access-Control-Allow-Methods and Access-Control-Allow-Headers to specify which methods and headers are allowed.
2. Update your ELB (Elastic Load Balancer) settings:
   • Ensure that the ELB is configured to forward the Origin header from the client request to your backend.
   • You might need to add a new rule or update an existing one in your ELB's listener settings.

it's not helping me, origin i set up already, but your check health can touch server with header origin which allowed
