[bug] Oncall doesn't start when referencing Azure Postgres DB

[flockoftanks]

Hey All,
Open Source
v1.2.21 (but was also happening in 1.1)
I submitted another ticket that postgres and mariadb weren't working while using the chart, so I created a postgresql db in Azure and referenced those instead:

Here's my original ticket: #1727

This is the closest I've gotten to working but there seems to be something wrong still. I'm getting the following error:

Warning: inverse host lookup failed for 20.185.0.143: Unknown host
