Resolution

Investigate whether any frontend Load Balancer (LB) or intermediate network component (such as WAF, reverse proxy, or firewall) is blocking or filtering this request. 
Suggest to check:

• Load balancer access logs
• URL path filtering or security rules
• HTTP response codes returned by the LB
• Whether the request is forwarded to the backend service correctly
