localserver

I have 2 issues. first: I was on my browser the ERR_NETWORK_ACCESS_DENIED error when i try to get to the R local help server ( http://127.0.0.1:xxxx../doc/html/Search?results=1 ) the second I had, when I launch android studio:; the message Internal HTTP server disabled: Can not start internal HTTP server. Git integration, JavaScript debugger and LiveEdit May operate with errors. Please check your firewall settings and restart Android Studio I try several solutions found on intrnet: flushing dns, restating winsock, disabling antivirus ... without success Last resort, I thought of a conflict

How do I allow any device, e.g., iPhone, to connect over a WLAN to my Mac's localhost server? On my Mac, I'm running a "Hello World" HTTP Node.js server that serves a page, which Safari opens successfully, at http://localhost:1337 . And, running ipconfig getifaddr en1 in Terminal outputs 192.168.1.9 . But, Safari, on both iPhone & Mac, displays "Safari can't connect to the server" when it tries to open http://192.168.1.9:1337 . I don't think this should involve port forwarding because I only want the HTTP server to be available privately, not publicly. Related: Accessing localhost from iPhone
