The problem is that your server seems to be VERY slow to respond to the initial connection request. It might be many things (including lack of entropy on your server). It could also be a firewall in between etc. I strongly suggest to look at your server configuration, logs and monitoring and try to fix the root cause. BTW. We also recently saw similar problems in our CI environment, so we believe this is something environmental in one of the recent releases of debian (if you are using docker). Since we are not 100% sure what caused it (and what is the fix that latest ssh provider also has the functionality to increase banner timeout: https://airflow.apache.org/docs/apache-airflow-providers-ssh/stable/index.html#id2)Add a retry with wait interval for SSH operator (#14489) You can upgrade to latest ssh provider and modify the SFTPSensor (create your own copy) to add the banner_timout parameter. -- This is an automated message from the Apache Git Service.
