If I use either Mist or MetaMask, I get the error message:

Unable to connect to http://localhost:8545. Invalid JSON RPC response: ""

How can I connect to the Remix localhost?


You're waiting for the Remix team to add support. Currently they only support local nodes running, but marked the issue as "soon" on October 4th:



I haven't actually used Mix, the Dapp IDE myself, but based on their documentation, and that error, it looks like it requires a local node running, and does not take advantage of an injected web3 API, the way Mist and MetaMask provide.

  • I am running a local geth node with Mist :/ Nov 3 '16 at 20:31
  • I'm not sure Mist actually exposes its local geth node's port. MIX definitely requires a server on port 8545.

  • You are confusing Mix with Remix. Mix was discontinued in favor of Remix.
