Cluster can't return own entries

[AugustasV]

I noticed that than I was following tutorial command failed

dig -p 5053 +tcp @localhost localtargets-roundrobin.cloud.example.com && \
dig -p 5054 +tcp @localhost localtargets-roundrobin.cloud.example.com

After running make terratest command received that error
