| // 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. |
