Everything is working now after fixing Problem 4 and configuring from IP to domain name.
I was attempting to get nodebb working on strictly the IP address. However, I was able to get the domain linked by utilizing Custome Resource Records settings of:
Name / Type / TTL / DATA @ / A / 1h / xx.xxx.xx.xx * / A / 1h / xx.xxx.xx.xxThen, I simply changed my ip address to the domain and now everything is working perfectly. I am not sure why, though.
