I have developed a spring boot app (User Registration app) that has one rest API. The rest API inserts the data in a MySQL. The application and database have been deployed in GCP Kubernetes and everything was working fine as I was using network load balancer. Now I am trying to use NGINX Ingress Controller and Path-based Ingress routing. A network load balancer is pointing to NGINX Ingress Controller and Load Balancer IP is tagged to a wild card host name in Cloud DNS.
From PostMan application whenever I am trying to hit the "User Registration App" using the DNS url it's throwing an error:
<html>
<head>
<title>405 Not Allowed</title>
</head>
<body>
<center>
<h1>405 Not Allowed</h1>
</center>
<hr>
<center>openresty</center>
</body>
</html>I am trying to provide all the details I have right. Can provide more details if required. I am not able to understand why NGINX server is throwing "405 Not allowed error".

Please help.
The resolution is here. Changed the URL path and used a registered domain to access via the internet.
