Suddenly lost access to Azure resources from Visual Studio 2022 version 17.5.5

Question

I have a number of web apps running in Azure that I can no longer connect to from within Visual Studio 2022 to debug. The publish profiles for each of these apps is still ok as I can publish to each with no problem. But as soon as I try to attach a debugger, I get an error saying "Azure resource is unreachable".

I have updated Visual Studio 2022 to latest release and that has not fixed the problem.

I have also logged out of all accounts and logged back in.

It seems like Visual Studio is either having a problem authenticating against Azure or reading resources from Azure.

If I try to add a connected service, I see no resources to select and just get prompted to sign in with a different account.

Can anyone help resolve this?

Thanks

Nick
