New Install "MYSql Server Has Gone Away"
+1 for the xkcd reference.
There's some work being done on SSL but for the &quot;server exists&quot; error this is a known issue for azure. See https://lab.civicrm.org/dev/core/-/issues/1206
Briefly, just comment out the body of the check it mentions and instead make it always return TRUE: https://github.com/civicrm/civicrm-core/blob/5.16.2/install/index.php#L1036
