Django Failed to establish a new connection <urllib3.connection.HTTPSConnection>

Using Django
1

hello, I use Django 2.2 and I have an api that is connected to two Esx servers.

  • a = 10.131.171.80
  • b = 10.131.171.90

everything works perfectly, except that during my test when I add a third fake server, it tells me that the server does not respond because connection time out. So the error is handled and I don’t have a yellow page from Django.

Except when enter fourth server this time private ip like 172.16.15.15 I have an error Max retries exceeded NewConnectionError(<urllib3.connection.HTTPSConnection’>

But when I use a public IP like 1.1.1.1, I don’t get any error.

What I would like is to handle the error better when someone enters a private IP.

what’s weird is that on local env localhost everything works even with private ip but when I am in my test server it doesn’t work.

My full traceback
Here is my api.py file.
