Well. @blotouta2. I think this issue discusses 3 or 4 different problems. So
your comment is pretty meaningless. Also the issue is clsoed so it's likely
it's a different issue altogether.
If you REALLLY want to get help, just open a new issue and provide all the
details you can (and ideally a reproducible case). Or if you do not have
reproducible case - provide as much information as you can and open a Github
Discussion
And BTW. if you are using an older version of Airflow, just upgrade to the
newest and check - Airlfow follows SemVer, so it should be rather safe to
upgrade.

> Priority: Major

> Sometimes when a task fails, the log show the following
> {code}
> *** Log file does not exist:
> /usr/local/airflow/logs/my_dag/my_task/2019-07-07T09:00:00+00:00/1.log***
> Fetching from:
> http://:8793/log/my_dag/my_task/2019-07-07T09:00:00+00:00/1.log***
> Failed to fetch log file from worker. Invalid URL
> 'http://:8793/log/my_dag/my_task/2019-07-07T09:00:00+00:00/1.log': No host
> supplied
> {code}
> I believe this is due to the fact that the row is not committed to the
> database until after the task finishes.
