Hi Cerbos team, just a small question I do implement a agent service that calling cerbos to check resource in JS like this

const cerbos = new Cerbos("my_domain", { tls: true });

It's working well and I do want to do it in Rust

let options =
        CerbosClientOptions::new(CerbosEndpoint::HostPort("my_domain", 3592));
 let mut client = CerbosAsyncClient::new(options).await?;

it said CheckResources call failed, i'm not sure that it because I add 3592 or not, butI add it due to CerbosEndpoint require it. May you direct me to the right way?

Hi, usually Cerbos serves HTTP on 3592 and GRPC on port 3593 - the Rust client uses GRPC, so maybe try connecting to 3593 instead?

still get message "CheckResources call failed"

Which JavaScript client are you using -

@cerbos/grpc

or

@cerbos/http

?

@cerbos/grpc

When it's deployed to

my_domain

- is that behind a load balancer or something? Perhaps port 443 on

my_domain

is being forwarded to the Cerbos server?

no load balance just kube,

Nope, I mean that if you can just pass

"my_domain"

with no port in the JS client, then that would be defaulting to port 443. So maybe try changing

3592

to

443

in the Rust client options.

oh, working now, thank you for you time and helping
