[Bug]: grpc server address does not follow app.toml

[JoowonYun]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

There is a config in app.toml that can set the address of the grpc server.

In most cases, 127.0.0.1 will be used, but there are sometimes when internal IP or DNS must be used depending on internal policy.

cosmos-sdk/server/start.go

Line 501 in 03bca7b

grpcAddress := fmt.Sprintf("127.0.0.1:%s", port)

At that point the problem occur. Is there any other reason to hard code it?

Cosmos SDK Version

0.46, 0.47 and main

How to reproduce?

So what's the exact problem?

[JoowonYun]

We are running multiple cosmos nodes on one machine.

Without changing the port, we want to specify an internal IP and listen to 9090 grpc for each specific address.

For example,
gaia : 10.1.1.10:9090
juno : 10.1.1.11:9090

There is an IP that grpc listens to in app.toml, but I am curious as to whether hard coding is used instead of using the value.

dont see a reason to hardcode it, we can just default it 127.0.0.1

The current code does not use the default value. In the grpc address value of app.toml, the address is ignored and only the port is used. And it uses the hard coded address 127.0.0.1.
