Re: [D] Could not read served logs: Invalid URL 'http://:8793....': Not host supplied [airflow]

GitHub user mateotronce added a comment to the discussion: Could not read served logs: Invalid URL 'http://:8793....': Not host supplied

Hi! I'm using Airflow 3.0.6, and the solution to my problem was:

1. Add this command in the worker section of docker-compose.yml:

command: ["celery", "worker"]

2. In the common environment block, set the concurrency:

AIRFLOW__CELERY__WORKER_CONCURRENCY: 4

This works well for my virtual machine, which has 2 CPU threads and 8 GB of RAM.
