Attempting MQTT connection...Client ID: WIFI-Display-0029DCD7
failed, rc=5 try again in 5 seconds

Did you check what state 5 means? https://pubsubclient.knolleary.net/api.html#state

It is 

Code:

MQTT_CONNECT_UNAUTHORIZED

 - the client was not authorized to connect

First I would try to make sure you can connect to the broker from your computer with for example mosquitto_sub.

I suspect you have OpenPlotter's own Mqtt server configured with a username/password and your client is trying to connect to that.

Try changing the SK mqtt gateway's port something else, like 11883 and adjust your esp code accordingly. There should be also error messages in your RPi's syslog complaining about the gateway's mqtt broker (Mosca) not starting, if there is already the OpenPlotter-managed mqtt broker occupying the port 1883.
