Please check that your Ethereum client:

- is properly configured in your Truffle configuration file (truffle-config.js)
Hi @123995566, and welcome to the Infura community!
Have you double-checked that your Ethereum client is running, accepting RPC connections, accessible over the network, and properly configured in your Truffle config file? I would suggest checking out this tutorial on the Truffle site about using Infura in tandem with Truffle.
It sounds like the error you’re running into has to do with one of the above issues. If you’ve double-checked all of that and are still getting an error message, please send over the specific error message and we’ll do our best to help you out!
