# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
