The IP-Address of consoles.hadoop-workbench could not be found

[#1]

I could successfully deploy CDSW 1.4.2 on my CDH 5.14 with the Cloudera parcel.

If I create a new project and open the workbench I get this error message on the right side of the workbench:
"The IP-Address of consoles.hadoop-workbench... could not be found"

All the initial templates (Python, Scala, R..) gave me the same result.

How can I resolve this problem?

Grateful for any help!

The problem could be solved with setting up the Wildcard DNS Subdomain for CDSW properly.

(CDSW 1.4.X documentation page 51)

Thanks.
