ISSUE TYPE

• Bug Report

COMPONENT NAME

I am using the following connection variables:
ansible_connection: ansible.netcommon.httpapi
ansible_network_os: cisco.nxos.nxos

I tested several modules from the Nxos collection

OS / ENVIRONMENT

Rocky Linux 9.3
Cisco Nexus 9300v nxos 9.3.4

STEPS TO REPRODUCE

- collections:
  - cisco.nxos

  gather_facts: no
  hosts: nxos

  vars:
    ansible_connection: ansible.netcommon.httpapi
    ansible_network_os: cisco.nxos.nxos
    ansible_user: ansible-cisco
    password: test123

  tasks:
  - name: Change interface from L2 to L3
    cisco.nxos.nxos_interfaces:
      config:
      - name: Ethernet1/6
        description: "##Config from ansible"
        enabled: true
        mtu: 9216
        mode: layer3

EXPECTED RESULTS

What is expected is that Ansible connects to the Cisco Nexus switch and performs configuration on the interface

ACTUAL RESULTS

In the current result I always receive this SSH error, even using nxapi as the connection method.

Here is what I have in the 'all' file under the '/group_vars' directory.

ansible_connection: httpapi
ansible_httpapi_use_ssl: yes
ansible_httpapi_validate_certs: no
ansible_network_os: nxos
ansible_user: admin
ansible_httpapi_pass: somepassword

In my lab I am running 9.3(9).bin, and this works with no issue.
