Hello,
We set up a AKS with a private DNS zone, so we didn't need to use the external address for AzureSQL and MySQL, keeping all the trafic internal in our vlan. It was working great for the last 105 days (the amount time the AKD is up), till yestarday when sudenly the AKS stopped resolving the DNS zone, and all the hosted pods lost connection with their databases.
We deleted the custom DNS zone and recreated it with all the same records, with no luck.
As a workaround we changed all the pods to "talk" using the MSSQL and MySQL IP address, it worked fine.
We have other resource group with the same construction that is working fine.
Our AKS version is 1.18.14.
Thanks in advance!
