# Troubleshooting

<details>

<summary>Can't connect to the Replication Server</summary>

* Is the [Replication Server](/2.3/manual/replication-server.md) running?
* Is the Replication Server using the same schema as your project?
  * Ensure you have [baked](/2.3/manual/baking-and-code-generation.md).
  * For local RS, shut down the the Replication Server and launch it again.
  * For cloud RS, ensure you have uploaded the schema to the cloud, then retry.
* Are you on Windows and have text selected in the Command Prompt that is running the Replication Server?
  * Press **Esc** with the Command Prompt having focus to clear any selected text and resume the application.
  * You can also disable the **Quick Edit Mode** in **Command Prompt's Properties** to make it more difficult to accidentally select text. You will then need to select **Edit > Mark** (or press **Ctrl + M**) before you can select text.
* When starting the Replication Server locally, ensure you only have one running on a given port, and that port is not used by any other application.
* If the error persists, get in touch with us.

Make sure you've [baked](/2.3/manual/baking-and-code-generation.md) and check on the Networked Prefabs window that your prefabs show no issues.

* Are you connected to the Replication Server? Check the [CoherenceBridge](/2.3/manual/components/coherence-bridge.md).
* Do you have at least one [CoherenceLiveQuery](/2.3/manual/components/coherence-live-query.md) in the scene, and is it framing the gameplay?
  * **Tip:** You can set it to radius 0 so it encompasses the whole game space.
