Starting Web App Builder

[PhilipHughes]

When starting web app builder 2.4 I complete the url to my portal.  click continue and get

invalid redirect_uri  error 400

Hope this helps FAQs - Web AppBuilder for ArcGIS (Developer Edition)

What should I do when I try to set the App ID and encounter an Invalid redirect_uri error?

It is indicated that the URI of Web AppBuilder is not added or set correctly in the Redirect URI list when you registered the App ID for Web AppBuilder in the ArcGIS portal. Complete the following steps:

1. Go to /server directory of the Web AppBuilder installation, delete signininfo.json file.
2. Review step 4. Update the existing App ID with the correct redirect URIs. see View and update app registration info. Alternatively, you can create a new App ID from the scratch.
3. Refresh the browser running Web AppBuilder.
4. Provide your App ID again, and click Continue.

Thank you

Strange this working previously.  I deleted the application from portal.

reregistered the application following the instructions.

Now when entering url for app builder

screen comes up with my portal url

green tick

click continue

takes me to portal signin

complete username and password, click sign in

starts web app builder

returns to the screen with portal url

This obviously an endless loop

Phillip,

   Because you are using Portal make sure your redirect urls are https protocol.

Hi

This is what I have on the settings for the registered info,  if I remove http then I get the redirect error,  this results in loop when trying to start the builder,  I get an option to approve the application in portal but it simply returns to the portal url screen

https://unsoa-nbo-gis2.unsoa.dpko.un.org

Phillip,

   So unsoa-nbo-gis2 is the machine name and unsoa.dpko.un.org is domain name?

[PhilipHughes]

Yes that is short name and the domain of the machine with developer app builder on

  I see an error when firebug enabled but it is to quick for me in the console and then clears as it returns to

[RobertScheitlin__GISP]

Since Portal only uses https urls there is no need to have the http url in your redirect. It is strange that

if I remove http then I get the redirect error

That makes no sense. You will probably be better off contacting esri tech support as I don't see anything wrong with what you are saying you have tried.
