RHUI 4 Takes Over in AWS, Bringing New DNS Data

With the transition to RHUI 4, new host names and IP addresses are used. If you have firewall rules, proxy settings etc. that worked with RHUI 3 host names or their original IP addresses, you are likely affected, and will need to change these rules or settings to allow the new host names or IP addresses. Note that the old host names still exist, and are used by clients running rh-amazon-rhui-client version 3, with the exception of RHEL 9 clients, which already communicate with RHUI 4. In May 2022, the rh-amazon-rhui-client package was updated in AWS RHUI client configuration repositories for RHEL 8, 7, and 6. With this update, VMs communicate with RHUI 4 directly.

Here are the hostnames and IP addresses of client-facing RHUI 4 servers in AWS:
