ERROR Failed fetching torrent: Peer certificate subjectAltName does not match host, expected <IP>. Why an IP?

Explorer

Hello,

How is Cloudera determining the 'host' part in this message?  Running CDH 6.3 and receiving the following:

 

ERROR Failed fetching torrent: Peer certificate subjectAltName does not match host, expected 10.3.0.134, got DNS:srv-c01.mws.mds.xyz, DNS:cm-r01nn01.mws.mds.xyz, DNS:cm-r01nn02.mws.mds.xyz

 

Yet the reverse and forward lookup work just fine.  Why is it receiving an IP for the host?  Not able to make heads or tails out of the code yet.

@TCloud What is your certificate saying I am interested to see the SAN entries there so that I can co relate this. 

CM always expect the FQDN almost everywhere just an FYI. 


Cheers!
