VSX Clustering R80.20 DNS resolving error msg


I am seeing constant Alert error messages in our logs with reason: Firewall - Domain resolving error. Check DNS configuration on the gateway (0) .

Here are the statistics: R80.20, running on VSX, JHF Take 103 applied, 

Initially I thought the issue was being caused by the fact that in VSX the DNS servers for each context are the same (SK152873 - a large oversight if you ask me but) so with some redesign I was able to find 3 common DNS targets that would work in this scenario. Once that was applied, I still am seeing tons of these alert errors.

From the CLI I am able to confirm that all of the VSX contexts resolve DNS using dig/nslookup etc so I am not sure why I would be seeing this behavior
