# Cannot Connect to a DApp

If you’re having trouble connecting [Kastle](https://kastle.cc/) to a decentralized application (dApp), here are a few things to check before reaching out:

***

### **Network Mismatch**

If the dApp is on a different network than the one currently selected in your wallet, Kastle will automatically prompt you to **switch networks** (in the extension).

* Approve the pop-up to switch to the correct network.
* If you don’t see the prompt, refresh the dApp page and try connecting again.

***

### Unsupported Network

Some dApps may run on networks not yet supported by Kastle.

* In this case, please let us know via our [**Telegram Feedback Channel**](https://t.me/kastlewallet) so we can review and consider adding support for that specific network in a future update.

***

### Known-Compatible dApp Fails to Connect

If you’re trying to connect to a **dApp that already supports Kastle** (or is officially listed as compatible with Kastle Mobile) but still encounter errors:

1. Take note of the steps that lead to the connection issue.
2. Contact us through our [**Telegram Feedback Channel**](https://t.me/kastlewallet) and share those details.

Our team will review your case and guide you through the troubleshooting process.

🪙 **Tip:** Make sure your Kaspa wallet is unlocked and you’re using the latest version of Kastle before attempting to connect again.
