when i want open PRIVET NETWORK on METAMASK it wont open. i try it in two PC on same local ethernet
it might be a problem with testrpc, potentially it can't listen on the localhost:8545 for different reasons (firewall, another process listening on the same port,etc..).
restart it and check if the port is already open :
netstat -aon | find /i "listening" | find "8545" // for windows
netstat -na | grep -i LISTEN | grep 8545 // for linux
otherwise run it and specify different port using
