Web AppBuilder Apps are missing by changing portal name

[James_001]

Hi,

Recently we have changed our organizational portal url for arcgis online. It was something like  http://myold.maps.arcgis.com  to http://mynew.maps.arcgis.com . After changing the new name for portal all web appbuilder apps become missing, although I can see them in my directory G:\WebAppBuilderForArcGIS\server\apps. I already registered the url to app redirect page. Also, this was the first error

"You are currently signed in as: 'irfan.afsar_myorganization'. You do not have access to this resource: https://myold.maps.arcgis.com/sharing/rest/content/items/123xyz1234abcd9879(changed)". 

To fix this error I open my app config.json and changed my new portal Url in both for app and map location.

Now i can access and edit  my app by direct url http://myapp:3344/webappbuilder/?id=29 .

But in the web appbuilder template no app available.

I really appreciate any help!

Irfan,

  Well you are in a very difficult spot there. The only way that I am aware of to fix your issue is to start a new WAB install (in a new file location, do not delete or overwrite the old one) and create a new app and copy the contents of the old app 29 into the new apps folder (i.e. apps/2).
