2020-05 Cumulative Update for Windows Server 2019 (1809) for x64-based Systems (KB4551853) BREAKS Docker/Swarm networking RRS feed

  • Question

  • Windows Server 2019 running Docker/Swarm, ingress network was working fine until this was installed:

    2020-05 Cumulative Update for Windows Server 2019 (1809) for x64-based Systems (KB4551853)

    This broke something with the ingress network such that no traffic could enter through any exposed/published ports.

    Uninstalling this update made it all work again.
