Do you have the minor version of RHEL7 you are using? I brought up RHEL7 from AWS to try reproducing this... Not sure if this is already fixed or if I am not using the correct RHEL7 version.

My RHEL version I used

[ec2-user@ip-10-0-11-8 ~]$ cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.7 (Maipo)

Thanks very much for your response @jswongF5. I'm also using AWS, I have tried again there and was able to reproduce the issue.

[ec2-user@ip-x-x-x-x ~]$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.9 (Maipo)

Can you share the AMI ID you are using? I just tried with the following:

AMI ID: ami-0e4a9c85c36c8d230
AMI Name: SupportedImages RHEL-7.9 20220213-3bc3b5ac-2cf9-4a76-a1d3-dbc2bce20f69

I am now using the same version as you.

[ec2-user@ip-10-0-8-174 ~]$ cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.9 (Maipo)

If you scroll up a bit, does it look like it installs pip?

TASK [ansible-role-nginx-management-suite : (Python 2) Get version 2.7 'pip' script] ************************************************************************************************************************************************************
changed: [35.89.85.176]

TASK [ansible-role-nginx-management-suite : (Python 2) Check if 'pip' binary exists] ************************************************************************************************************************************************************

TASK [ansible-role-nginx-management-suite : (Python 2) Install 'pip' version 2.7] ***************************************************************************************************************************************************************
changed: [35.89.85.176]

When you ssh into your VM, what pip version does it look like it have?

[ec2-user@ip-10-0-8-174 ~]$ pip --version
pip 20.3.4 from /usr/lib/python2.7/site-packages/pip (python 2.7)

Also, what version are you using (ansible-galaxy list)? I just released a new one 0.3.0 (worth a shot although I am not entirely sure what would fix it).
