After mailcow reboot GUI not loading.

kdiamond

When I reboot my Ubuntu VM, instead of the Mail Login page, it will show the “What is happening page”.

I wait for 20 minutes, but nothing changes. I reboot one or two times and GUI comes back immediately after the boot. Any ideas? Mailcow version: 2025-10

Thank you

kdiamond You should update to 2025-10a. Seems like you are affected by the JIT issue.

Try

docker compose down
docker compose up -d

Thank you for your replies.

I did update to 2025-10a, rebooted, and the GUI started normally.
