Solution 1:

In which context do you see this problem ? Navigating ? Saving an item ? Jenkins CLI / REST API calls ?

To directly address this problem, you may use the Jenkins option --httpKeepAliveTimeout that default to 5000 (for 5 seconds) and set a higher value. See jenkinsci/winstone for more details.

This could well be due to Jenkins being overloaded and not being able to serve resources in time.
