PWSWeather setup

I have been trying to set up PWS weather for some time now to use with Weather Display and Tempest Weatherflow. It was working 8 months ago and then stopped. I have tried everything and was able to get 1 (ONE) manual observation to go about 4 days ago by using the tempest API key for PWS as my password…and anything else after that does not go (invalid station id/password)

So is there a step by step documentation that I can follow that shows how to set this up? I am using a MAC and Weather Display 10.37 for Mac build 378
