Metamask Error: ERR_CLEARTEXT_NOT_PERMITTED while running Dapp on Android

As an avid cryptocurrency enthusiast, you’re likely no stranger to the world of Web3 and blockchain technologies. However, when using MetaMask browser on your Android device to connect to a decentralized application (Dapp), you may encounter an error code ERR_CLEARTEXT_NOT_PERMITTED. In this article, we’ll explore what this error means, why it occurs, and most importantly, how to resolve it.

What is ERR_CLEARTEXT_NOT_PERMITTED?

ERR_CLEARTEXT_NOT_PERMITTED is an error that occurs in the browser extension of MetaMask on Android devices. This error typically arises when you attempt to interact with a smart contract or access sensitive information using your Web3.js library without proper authorization. In other words, it’s an “access control” issue.

Why does ERR_CLEARTEXT_NOT_PERMITTED occur?

There are several reasons why ERRCLEARTEXT_NOT_PERMITTED might occur:

• Insufficient permissions: The Dapp you’re connecting to may not have the necessary permissions to access sensitive information or interact with your account.

• Incorrect authorization flow: The Web3.js library may not be configured properly, leading to insufficient permission checks or inadequate authorization protocols being used.

• MetaMask extension issues: Sometimes, the MetaMask browser extension can cause conflicts or errors when accessing Dapp code.

Troubleshooting steps

To resolve the ERRCLEARTEXT_NOT_PERMITTED error, follow these troubleshooting steps:

• Check your MetaMask permissions

  : Ensure that you have granted the necessary permissions to the Dapp you’re connecting to. You can do this by navigating to Settings > Advanced Settings > Account Management and granting access to any required permissions.

• Verify authorization flow: Review your Dapp’s code to ensure it uses proper authorization protocols, such as Web3.js’s eth_requestAccounts() or web3.eth.currentAccount(). Additionally, verify that you’re passing the correct account ID or private key to the function calls.

• Inspect MetaMask browser extension settings: If using a third-party MetaMask browser extension for your Android device, inspect its settings to ensure it doesn’t interfere with Web3.js functionality.

• Test Dapp code in a different environment: Create a new Dapp project and test it in a different environment (e.g., on the same Android device) to isolate any issues caused by specific MetaMask browser extension configurations or errors.

Additional recommendations

If none of these steps resolve the issue, consider:

• Reaching out to Metamask support: Contact MetaMask’s support team for assistance with troubleshooting and debugging.

• Checking Dapp documentation: Review the official documentation for your Dapp project to ensure it uses proper authorization protocols and permissions.

• Upgrading Web3.js library: Ensure you’re using the latest version of Web3.js, as older versions may have introduced or fixed this specific error.

By following these steps and recommendations, you should be able to resolve the ERR_CLEARTEXT_NOT_PERMITTED issue while running your Dapp on Android with Metamask. Happy debugging!
