I've set up a connection between RDS and Skyvia. It has worked very well ... until yesterday.
My security rules in AWS permitted 40.118.246.204/32. Once I hit the problems yesterday, I also allowed
40.118.246.0/32
40.118.246.0/24
40.118.0.0/32
40.118.0.0/16
40.118.0.0/24
The only way I can make it work is to open up my RDS instance to all incoming traffic. If I do that, Skyvia can connect.
Is it possible that Skyvia is using a different port for SQL queries?
