allowed_cidr_blocks of anything but 0.0.0.0/0 doesnt allow traffic through

First of all, thanks for the tutorial, it is extremely helpful.

I'm trying to deploy a FastAPI app using the same method as this tutorial. I am using Mongo atlas as the database, so the only real change is that I dont need to deploy a database in the VPC.

I have got everything setup and working, however when I put anything but 0.0.0.0/0 for the allowed_cidr_blocks in the user.tfvars file, I can't access my application.

I tried the example:

allowed_cidr_blocks = ["99.99.99.99/32"]

As well as allowing a range of ports:

allowed_cidr_blocks = ["99.99.99.1/24"]

However, this came up with the error message:

Error: "99.99.99.1/24" is not a valid IPv4 CIDR block; did you mean "99.99.99.0/24"?

So I tried 99.99.99.1/24 as well but that didn't work either.

Do you have any advice on what values I should be putting here to fix this?

Thanks a lot for any help!
