Not able to connect to Ethereum node in web browser

Question

I am running geth on my VM. Everything runs fine on my machine but I am facing issues while connecting it to Web browser

I used this command to launch the nodes but I cannot connect to them through my browser

geth --networkid 8545 --genesis ~/genesis_block.json --datadir ~/.ethereum_sample console

I'm getting this error:

CONNECTION ERROR: Couldn't connect to node http://localhost:8545, is it running?

This is what I use to set the provider in the browser console:

web3.setProvider(new web3.providers.HttpProvider("http://localhost:8545"));

By default, geth listens only to localhost. You might want to try binding it to all addresses with --rpcaddr "0.0.0.0":

geth --rpc --rpcaddr "0.0.0.0" --rpcport 8545 --nodiscover --networkid "$NETWORKID" --datadir ~/.ethereum_sample --genesis ~/genesis_block.json
