Issue

• Run your CJP Private SaaS Edition service under your own domain (change from http to https with a wildcard certificate) give an error:

  the <HOSTNAME> does not appear to be a valid hostname"
  

  domain-name-change failed
  

Environment

• CloudBees Jenkins Enterprise (CJE) - AWS/OpenStack/Anywhere

Resolution

Please refer to the Change Domain Name and/or Enable SSL to see the how to change the domain name and see whether you can register a wildcard DNS entry.

You need to configure your domain_name and path_mode in cluster-init.config. Here is an example:

[tiger]
...
domain_name = cje.<YOUR_DOMAIN_NAME>
domain_separator = . 
path_mode = yes

The path_mode = yes is only necessary if wildcard DNS cannot be used. If you can register a wildcard DNS entry, then set path_mode = no. Refer to Domain options guide and DNS entry for more information.
