### Description

I make the client like this:

```auto
weaviate_client = weaviate.connect_to_weaviate_cloud(
            cluster_url=WEAVIATE_URL,
            auth_credentials=Auth.api_key(WEAVIATE_API_KEY),
            skip_init_checks=True
        )

```

Deploy my python backend on azure container app but it keeps throwing in the console:  
stderr F debug\_error\_string = “UNKNOWN:Error received from peer {created\_time:“2025-04-08T13:56:17.76001071+00:00”, grpc\_status:4, grpc\_message:“Deadline Exceeded”}”

### Server Setup Information

Serverless cluster hosted by Weaviate.

### Any additional Information

hi @bamibestelt !!

Welcome to our community 🤗

For any issues with a cluster hosted in our cloud, the best place for support is opening a support ticket from:

> **[Weaviate Cloud](https://console.weaviate.cloud/signin?callbackUrl=https%3A%2F%2Fconsole.weaviate.cloud%2Fsupport)**
>
> Weaviate Cloud

With that we can check the cluster logs and identify.

This can happen if the cluster is overwhelmed or while it is scaling (and HA is not enabled).

Thanks!
