I have changed GETH_HOSTNAME and APP_HOSTNAME to my ip from localhost . do i need to make additional changes before running it on a cloud ?

Thanks for the help

Change GETH_HOSTNAME to your Ethereum Geth node IP and APP_HOSTNAME should be only localhost or 127.0.0.1

I have the same issue..

my geth machine is NAT Network VPN on public cloud .

fowrd setting. wan: 8000 to lan: vm_address:8000 wan: 8545 to lan: vm_address:8545

and geth command line option is " --rpcaddr "0.0.0.0" --rpcport 8545 --rpccorsdomain "*" "

and edit the "start" section on the package.json . "start": "http-server ./app -a 127.0.0.1 -p 8000 -c-1" to "start": "http-server ./app -a 0.0.0.0 -p 8000 -c-1"

I will see the explorer screen by the my laptop on the chrome.

and connect to WAN IP:8545 by the Metamask.

but An error has occurred.
