Azure Enterprise Apps – Unable to update application proxy settings
Office 365
(Azure Application Proxy)

When trying to change an Enterprise App -> Application Proxy -> External Url to a custom URL it displays the error message “Application proxy settings Unable to update application proxy settings” when trying to save it.
To fix:
- Go to Azure Active Directory
- Select “App registrations”
- Select the affected app
- Select “Authentication”
- If the domain is the list of URIs then delete it
- Save the app
- Try to change the External Url again
The app should then allow you to change the External Url and save it.
