# How do I connect to W&B Self-Managed?

[W\&B Self-Managed](/platform/hosting/hosting-options/self-managed) is a self-hosted deployment that runs in your infrastructure. Point the SDK and CLI at your instance URL instead of the [Multi-tenant Cloud](/platform/hosting/hosting-options/multi_tenant_cloud) API (`api.wandb.ai`). For login commands, `WANDB_BASE_URL`, and `--host`, see [`wandb login`](/models/ref/cli/wandb-login) and [Environment variables](/models/track/environment-variables).

## Verify the connection

```bash theme={null}
wandb status
```

Confirm the host matches your instance URL and the API key is present (masked).

## SSL / certificate issues

If your instance uses a self-signed or internal CA certificate, set the CA bundle before initializing W\&B:

```bash theme={null}
export REQUESTS_CA_BUNDLE=/path/to/ca-bundle.crt
```

## Switching between Multi-tenant Cloud and Self-Managed

To use Multi-tenant Cloud again, unset `WANDB_BASE_URL` and run `wandb login` without `--host`:

```bash theme={null}
unset WANDB_BASE_URL
wandb login
```

## Common issues

* **401 on `wandb.init()`**: API keys are not shared between Multi-tenant Cloud and a Self-Managed instance. Create a key on your Self-Managed instance profile.
* **Connection refused / timeout**: Check the instance URL and VPN or network access to your deployment.
* **License not recognized**: See [Why is my enterprise license not recognized?](/support/models/articles/enterprise-license-not-recognized).
