Bad DNS config while setting a custom domain

[QDespeisseTalan]

While preparing the installation, we specified a custom domain for our MAS instance. The domain is different from the Openshift's one.

During the MAS install, the OCP hostname is defined as apps.65e73b7612697b001299b3e7.cloud.techzone.ibm.com and this value is used to create the DNS CNAME records.
However, this configuration leads to dns_probe_finished_nxdomain.

To make the DNS work, I had to change the target host as router-default.apps.65e73b7612697b001299b3e7.cloud.techzone.ibm.com.
Attached, the YAML from the suite-dns task.
