I downloaded ArcGIS online for developers and was able to configure it to connect to my computer. I was able to successfully add in custom widgets to my online web app. Everything ran smoothly the first day but after restarting my computer the next day, nothing would work. Upon opening the links it says:
(my computer name) refused to connect
I just don't understand why it worked one day and not the other. Is there any extra steps I have to take to open it each day? I did not move any files before or after restarting my computer either.
