PyInstaller unable to package python-certifi-win32 and causing the JIRA connection throw SSL error Certification Verify Failed

I am trying to make a connection to JIRA server using python and below is code:

from jira import JIRA
server =  'https://jira.company.com:444/'
usrnme = input("Enter UserId: ")
pwd = getpass()
jira_instance = JIRA(server = server, basic_auth=(usrnme, pwd))

When this code is run in powershell, I used to get this error:

runfile('C:/Users/desktop/JiraConnection.py', wdir='C:/Users/desktop')

AttributeError: 'SSLError' object has no attribute 'headers'

To resolve this I installed python-certifi-win32 and everything works perfectly in powershell. Now, I want to make the code as executable and so used PyInstaller and it creates an executable but when I try to run and make a jira connection, I get the above error again. Is there a way to package this certificate verification in my code to solve the SSLError? Please help.
