I had got the same issue at our server. how to find out it?

The error suggests that IPv6 is not supported by the operating system. Closing, not a node bug.

You can edit the following files to fix this issue:
Either node_modules/react-native/private-cli/src/server/runServer.js for the latest versions
//return http.createServer(app).listen(args.port, '::', readyCallback); // IPV6 any IP
//return http.createServer(app).listen(args.port, '127.0.0.1', readyCallback);
return http.createServer(app).listen(args.port, '0', readyCallback); // IPV4 any IP

or

On earlier versions it was in:

node_modules/react-native/packager/packager.js

//return http.createServer(app).listen(options.port, '::', readyCallback);
return http.createServer(app).listen(options.port, '0', readyCallback);

This is running on Centos 5.9

It works for me

Thinks @nfranzmeier

it works for me, too.

but need a little change!

from

return http.createServer(app).listen(options.port, '::', readyCallback);

to

//return http.createServer(app).listen(options.port, '::', readyCallback);
return http.createServer(app).listen(options.port, '127.0.0.1', readyCallback);
