Flask pod results in Cannot GET / when another flask pod is accessed

General Discussions

I have 2 pods

containers:
pod1

  1. flask
  2. vue

pod2
1.flask
2.postgres

when I make api calls to flask of pod1, the pod2 results in Cannot GET and vice versa. when i recreate the pods and make api calls to flask of pod2, the pod1 results in Cannot GET.

What maybe the reason and how to resolve this?
