Absurd error when adding an authorized network

[Jose_Farinha]

I'm trying to add an authorized network to a GCloud MySQL instance, but I'm getting a stubborn error message saying that I need to use a CIDR (slash) notation, when I think I'm actually using it: 194.117.2.116/24, as shown bellow. "194.117.2.116" is in fact the address Google says is my public IP address.

Am I doing anything wrong? Has this already happen to anyone? 

Thanks for your attention.

Can you retry after updating it as - 194.117.2.116/32 as you are authorizing a single IP address only.
