TypeError: '<=' not supported between instances of 'str' and 'int' #5

I am apparently unable to make a connection to my MQTT broker, which exists on a different device; a Home Assistant box. The screen just displays: 

Connecting to 
MQTT broker...

Meanwhile, in my shell, I see:

/home/bigron/./ospiLCD-mqtt.py:256: DeprecationWarning: Callback API version 1 is deprecated, update to latest version

I realized that it the TypeError was due to the way the mqttPass was defined in Line 32; the quotation marks need to be removed from the variable declaration. With quotation marks, it thinks that the port number is a string, not a number. Unfortunately, that didn't solve all of the issues. It now has an issue with calling the client.

/home/bigron/./ospiLCD-mqtt.py:256: DeprecationWarning: Callback API version 1 is deprecated, update to latest version
client = mqtt.Client()
[Connected with result code 5]
[Connected with result code 5]

On line 254 it says:

client = mqtt.Client()

Apparently, this is attempting to connect with API version 1, which has been deprecated. I know that my MQTT broker supports version 5. I was doing some testing and can't figure out how to tell it to use version 5 but I did see a command to make it try version 2. If I change it to:

client = mqtt.Client(mqtt.CallbackAPIVersion.VERSION2)

With this, I get an error saying:

I am hoping I'm making progress but as of yet, I don't have it working.
