### What happened
Hello,
We have a lot of DAGs that we ran daily, but only at specific time of the
year. For that, we programatically pause and unpause the DAGs when they should
run. However, starting from Airflow 2.10.3, the unpaused DAG is no longer
triggered (it was working correctly in previous version of Airflow).
The only thing I see in the log file is the following:
```
[2021-10-10 22:02:35,058] {dag.py:2287} INFO - Setting next_dagrun for mydag
to 2021-10-09 22:21:00+00:00

triggered: False> successful
```
To force the DAG to run, I have to restart the scheduler, force run the
first task of the DAG, and then clear it.
I also tried to wait a day or two, but the DAG is never scheduled.
Please tell me if you need more information
Thanks a lot
