SSLError "UKNOWN_PROTOCOL" imaplib Python

Question

I am trying to connect to an email server with my own credentials in Python. The script works great until the exception "SSLError" shows up. Sometimes it occurs as soon as starting up the script or after running the script for a few hours. I created an exception for it, but that does not work.As long as the SSLError exception occurs, the script will not connect.. Someone please help as I am not a professional:

IMAP4_SSL_PORT = 993

while True:

    now = datetime.now()
    msrver = imaplib.IMAP4_SSL(host = 'myemailserver.com',port = IMAP4_SSL_PORT)

    unm = 'usernamehere'
    pwd = 'passwordhere'
    msrver.login(unm,pwd)

Here is the traceback:

Traceback (most recent call last):
File "C:\Users\ereyes\Desktop\TestScripts\Database Automation.py", line    16, in <module>

Thanks in advance!
