After the upgrade from Azure DevOps Server 2019 to 2020.1.2, it is impossible to switch users. Currently, this is being tested on a test ADS server
Original version: Edition: Azure DevOps Server 2019 Product Version: 17.153.29522.3 (AzureDevOps2019 Update 1.1)
The upgrade is done via azuredevops2020.1.2.iso Edition: Azure DevOps Server 2020 Product Version: 18.181.32404.7 (AzureDevOps2020 Update 1.2)
First logon works without problem and I have access to Azure DevOps Server 2020. When I do "Sign in as ...", I get the popup screen to enter new (or the same) credentials. I enter the correct credentials with enough permissions + click enter and the popup screen returns empty (every time). When I click cancel on the popup, I get the error "TF400813: Resource not available for anonymous access. Client authentication required."
If I go back to my URL http:/// after the failure, I can log in again with any user.
Does anyone have an idea how to fix this?
I tried the following: The first attempt was to directly install azuredevops2020.1.2.iso Second attempt I on the first attempt was to directly install azuredevops2020.1.2.iso on the second attempt I Installed azuredevopsserver2020.0.1.iso Installed devops2020.0.1patch9.exe (this was the patch that would resolve the issue, but the test still failed) Installed azuredevops2020.1.2.iso
