   First of all description/title of the problem is wrong. There is no way UI 
error cause task failure, because there is no possibility of doing so. The logs 
suggest that you are mixing cause with resulr
   
   This is not a reproducible case - and it looks like this is a deployment 
issue. It looks like some of your workers do not properly set their name 
properly - likely hostname-callable does not return the right host name 
https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html#hostname-callable
 (which would indicate temporary DNS problem in your Kubernetes).
   
   I'd recommend to follow: 
https://kubernetes.io/docs/tasks/administer-cluster/dns-debugging-resolution/
   
   More information is needed from various logs (including logs of what is 
happening in your Kubernetes when name resolution happens) is needed in order 
to make it qualifies as Airflow issue. 
   
   Switching to discussion unless more information is provided.
