In this article, you will learn how to fix the following error “IP Address UNREACHABLE: HTTP connection pool Max exceeded’.
Why was the Error “IP Address UNREACHABLE” Prompted?
The following error below is a result of a wrong IP Address used in the inventory list. For more information on Ansible authentication options, see the following guides on Kerberos and also this link.
Error as shown in the image below " IP Address UNREACHABLE: HTTP connection pool Max retries exceeded with url/wsman caused by NewConnectionError"
Since my focus is on Kerberos, see the article on how to configure Kerberos
192,168,178.43 | UNREACHABLE! => {
"changed": false,
"msg": "ssl: HTTPSConnectionPool(host='192,168,178.43', port=5986): Max retries exceeded with url: /wsman (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 8] Name or service not known'))",
"unreachable": true
}
The solution to fixing IP Address UNREACHABLE: HTTP connection pool Max retries exceeded with url/wsman caused by NewConnectionError
As you can see, it clearly stated “NewConnectionError”. Failed to establish a new connection because the IP Address had a comma (,) instead of a dot (.) in the host inventory as shown below.
– Correct the inventory file as shown above with the right IP Address and try again and try to oing the host inventory file as shown below with the following Ad hoc command below.
$ ansible all -i hosts -m win_ping
