// Node >=17 has different DNS resolution (see
|
|
// https://github.com/nodejs/node/issues/40702), it resolves domains
|
|
// according to the OS settings instead of IPv4-address first. The Karma server
|
|
// only listens on IPv4 address (127.0.0.1) by default, but the requests are
|
|
// sent to `localhost` in several places and `localhost` is resolved into IPv6
|
|
// address (`::`). So the run/stop/proxy request is unable to reach the Karma
|
|
// server and produces an error. To mitigate this issue karma force the
|
|
// IPv4-address first approach in Node >=17 as well.
