Troubleshooting from a Rookie

I am new to Cayenne and trying to make an initial connection. I have a NodeMCU (ESP8266) v1.0 that works fine with Blynk and other software. I have installed the Cayenne Library and the ESP board package in the Arduino IDE. Everything uploads fine to the board, but the Cayenne page just hangs on “Waiting for Board to Connect…” I’m not sure how to troubleshoot. There are very few components (ESP and Cable) and they work fine with other software. Ideas from the experts?

oops! Nevermind…I restarted things and it seems to be working. Told you I was a rookie.
