I had faced a similar kind of issue, for ip based setup you need to specify the domain name as the ip that you are going to use, this error is showing up because the ssl is ip based but the fqdns seems to be undercloud.com or overcloud.example.com.

I think for undercloud you can change the undercloud.conf.

And will it work if we specify clouddomain parameter to the IP address for overcloud? because it seems he has not specified the clouddomain parameter and overcloud.example.com is the default domain for overcloud.example.com.

What is the domain name you have specified in the undercloud.conf file?

And what is the fqdn name used for the generation of the SSL cert?

Hi Team,

We were trying to install overcloud with SSL enabled for which the UC is installed, but OC install is getting failed at step 4:

The procedure to create such files was followed using: 

Deploying with SSL — TripleO 3.0.0 documentation (openstack.org)

Idea is to deploy overcloud with SSL enabled i.e Self-signed IP-based certificate, without DNS. 

Any idea around this error would be of great help.
