Unable to test custom widgets or see widget in Web AppBuilder

Question

I've followed all the instructions here for creating a custom widget. I've put my widget in the C:\...\client\stemapp\widgets folder and also added the code below to the config.json file in my C:\...\client\stemapp folder. { "label": "MyWidget", "uri": "widgets/MyWidget/Widget" } When I try to test my widget using this URL http://:3344/webapp/?config=config.json I only get a blank screen. Upon checking the errors in the Chrome developer console I see that I have an error saying Failed to load resource: the server responded with a status of 404 (Not Found) followed by this URL http://:3344/http://:3344/sharing/portals/self?f=json&dojo.preventCache=1426103768809 Also, I am unable to see my custom widget in the Choose Widget panel of the Web AppBuilder. Can anyone help me with this problem please?

Haha, sorry I did not look to see that you posted the other question too. I am not sure how to help from here. Sorry.

Hi Stan,

Thanks for your help. Unfortunately the question you refer to was another

one that I posted which I have now marked as not correct. We have some

issues here in our corporate LAN with portal access. Not sure what the

answer is yet.
