"Create application service" The dialog does not receive information, the "Create" button is disabled

Question

I am trying to create empty ASP.NET 5 WepApplication and post it on azure , there is a problem that I cannot understand or solve, create app service dialogue does not seem to be extracting anything (it did some minutes ago) no Subscriptions , no Resource Group , no AppServicePlan , there is nothing, and some of these fields are not even edited, so Create Button always disabled, so there is no way to create a Wep application in App Services.

Please note that my credentials are entered and associated with my email, which has an Azure subscription and that's it.

Here are some screenshots that describe this:

Answer 1

I was able to fix this problem in Visual Studio 2017 by logging out of my account in Visual Studio and then starting up again.

Visual Studio can cache your credentials before starting a subscription. Logging out and back can cause this data to be updated.
