Warning
Chef Automate 4.x will not be available for download before the end of September 2022. We are working on making the upgrade process a seamless experience. Until then, you can download Chef Automate 3.0.49. Please get in touch with support for more information.
The Chef Automate High Availability (HA) cluster requires multiple ports for the front and backend servers to operate effectively and reduce network traffic. Below is a breakdown of those ports and what needs to be open for each set of servers.
