Docker-airflow: Problem connecting to WEB UI after docker upgrade

[vazl]

Hi,

Upgraded docker on Windows 10 today and now having issues with running container. The logs show the following error:

Running the Gunicorn Server with:
Workers: 4 sync
Host: 0.0.0.0:8080
Timeout: 120

Logfiles: - -

Did I miss something?

Thanks

I have the same problem, I also upgraded Docker recently. Please, is there any fix? I tried re-installing Docker but that didn't solve the issue.

EDIT / UPDATE:
I found a workaround.
I fixed it by un-installing Docker Desktop and installing a previous version (2.1.0.5 from https://docs.docker.com/docker-for-windows/release-notes/).
Of course I had to re build the images, but it finally worked in the end! Hope this helps you!

The problem was fixed as follows:

1. Reinstalled Docker
2. Started container without any dags and only added them once airflow was running
