Critical Fix: „Failed to get chain ID. Is your RPC URL correct?” Metamask
Metamask is a popular Ethereum wallet extension that allows users to store, send, and receive ether (ETH) on their computer or mobile device. You may have recently encountered an error message when trying to add the Anvil plugin to MetaMask when using the Windows Subsystem for Linux (WSL). This article will help you troubleshoot and resolve the issue.
What causes the issue?
The „Failed to get chain ID. Is your RPC URL correct?” error occurs when Metamask is unable to connect to the Ethereum blockchain using Web3.js, a JavaScript library for interacting with the Ethereum blockchain. The issue can be caused by several reasons, including:
- Incorrectly configured RPC (Remote Procedure Call) URL
- Network connectivity issues between WSL and Ethereum blockchain
- Plugin conflicts or unmet dependencies
How to fix the issue?
To fix this issue, follow these steps:
- Check your RPC URL: Double-check that you are using the correct RPC URL for your Ethereum node. You can find your node address by running
wsl --list-nodes
in a new terminal window.
- Check network connectivity: Make sure that WSL is connected to your Ethereum blockchain network. You can do this by doing the following:
- Open a new terminal window
- Run
wsl --connect "your-wsl-machine-name"
(replace it with your actual machine name)
- Verify that you are connected to the network using the
wsl --nodes
command.
- Disable plugin conflicts: Sometimes plugins can conflict with each other. Try disabling and re-adding the Anvil plugin to see if that resolves the issue.
- Update Metamask and Web3.js: Make sure you have the latest versions of Metamask and Web3.js installed on your machine. You can update it by running
npm install --global metamask
andnpm install web3
.
- Check plugin dependencies
: Make sure you have all the necessary dependencies for the Anvil plugin. You can check this by running
pip list anvil
(if you are using pip) ornode -v
and the version of Web3.js.
- Run MetaMask in a fresh WSL instance
: If you have recently updated the MetaMask extension, try running it in a fresh WSL instance to see if the issue resolves itself.
Additional Troubleshooting Steps
If none of the above steps resolve the issue, you can try the following:
- Check the Ethereum blockchain status by running etherscan.io.
- Verify that your Ethereum wallet is set up correctly.
- For further assistance, please contact the Metamask community or support forums.
Following these steps should resolve the „Failed to get chain ID” error. Is your RPC URL correct?” MetaMask by running it in WSL.
