I am on 6.7.0-rc2 but was having the issue on the release branch as well

 

192.168.0.100 is unraid

192.168.0.141 is my laptop

not sure why but i fixed it. One of my dockers is piehole and my unraid adapter had the piehole ip as a dns entry for DNS 1. I removed this dns entry from my unraid adapter and now the error is gone and the update for docker reports back in a few seconds
