CDSW worker status is false

Question

I added anew worker to the CDSW cluster and the status of this worker is false,

In the logs I gut this message:

Unable to connect to the server: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kubernetes")

@ronys The requirements are valid for all worker and master hosts.

All Cloudera Data Science Workbench gateway hosts must be part of the same datacenter and use the same network. Hosts from different data-centers or networks can result in unreliable performance.
A wildcard subdomain such as *.cdsw.company.com must be configured. Wildcard subdomains are used to provide isolation for user-generated content.
The wildcard DNS hostname configured for Cloudera Data Science Workbench must be resolvable from both, the CDSW cluster, and your browser.

So you have to make sure the DNS and wildcard with TLS host cert (if any) is properly configured. For reference use any of the working hosts.

@ronys This seems an issue with the TLS setup within CDSW. You have to make sure the wildcard domain is properly configured and then restart CDSW again to see if this makes progress.
