Problem A dockerized DOC application is running on Windows 10. After some time during which the computer has switched to sleep-mode, the application stopped working. The problem is that security tokens are created in the past making them invalid as soon as they are shared between micro-services. This has been known to happen with Docker Desktop 2.2.0.4 Solution This is due to a problem with Docker on Windows: the containers have their clock desynchronized from the actual computer clock causing dates inside the containers to be late compared to the actual date of the system.

Symptom When I want to give access to my drive to Docker, Docker is asking for a user/password to authorize this access. The problem is that I have a Windows 10 account without a password either because I’m using Azure identification or because I’m using fingerprints for identification. Solution You need to create a user for Docker. Follow the steps described in: https://forums.docker.com/t/how-to-share-windows-drives-with-a-user-without-password/22933/5
