No response from gunicorn master within 120 seconds after pointing to external postgres

Question

I am deploying airflow latest release using Docker, everything works fine until I point the database to an external Postgres Database. As soon as the database is pointed to an external database the webserver container doesn't get up.

The release is from apache/airflow:latest

The logs says the following

No response from gunicorn master within 120 seconds

What am I missing here ?

did you check the webserver container log? – Emelinaemeline

Yes, its in the screenshot – Humbug

This error comes when the number of workers running does not match the expected number of workers for a period of time. check the number of workers in airflow.cfg file, try reducing it to a smaller number, probably 1. – Radiophotograph

@Humbug were you able to get this resolved? – Perrone

I'm currently experiencing this issue as well. – Ormazd

@anshul_cached, try increasing the timeout for the master worker and reducing the number of workers. You can check this issue on github as well – Ormazd
