Authentication service is unavailable -- Xamarin.iOS Automatic Provisioning Windows VS 2019

Question

Authentication service is unavailable -- Xamarin.iOS Automatic Provisioning Windows VS 2019

Matt 46

1) Tried different accounts to include one that worked perfectly fine in the past.

2) I get the Authentication service is unavailable error whenever I try to select a team via Automatic Provisioning on windows vs 2019 community edition. (all updated)

3) I have already completed the step below with no success.

If the automatic provisioning process fails with the error message Authentication Service Is Unavailable, sign in to either App Store Connect or appleid.apple.com to check that you have accepted the latest service agreements.

Any ideas why I keep getting this message?

This is also an issue for me since upgrading to VS 16.9.3 as reported by myself and several others in the developer community (https://developercommunity.visualstudio.com/t/Error-adding-Apple-Developer-Account:-au/1380749?viewtype=all)
As a result, I am unable to create a new .ipa file to deploy our app to a replacement iPhone.
Please advise a fix/workaround asap.

I also have the problem across a variety of devices and VS versions. Attempting to resolve, I re-installed VS-Pre 10.2, reset my Mac keychain, deleted all certificates to continue having the issue when try to auto-provision. Where is the service hosted? If we need to install it, where do we get it?

I added this issue to a problem report in the Developer Community which I have been trying to debug which lead to encountering this issue.

Updating to version 16.10.0 fixed this issue.

Although it introduced a different issue, "MessagingRemoteException: An error occurred on client Build1610000228 while executing a reply for topic xvs/build/execute-task/#projectname/dcef6ea002fACTool
IOException: Sharing violation on path /#pathto/Library/Caches/Xamarin/mtbs/builds/#projectname/dcef6ea8f073d59dc1c36cb1f5a222f318d7bca40b05591396d2da9756e6eedb/Assets.xcassets/AppIcon.appiconset/Contents.json"

Uninstalling VS 16.10.0 and reinstalling 16.9.6 fixed the "new" issue.

Maybe this is the universe telling me to learn Swift and Xcode.

I started to create a separate problem report to discover numerous others have had this issue, MS supposedly has a fix to released soon and a workaround by someone using VS Mac has been found.
