WebClient failed to resolve domain name

Version

• vert.x core: 3.5.3
• vert.x web: 3.5.3
• vertx.web-client : 3.5.3

Context

I encountered an exception which looks suspicious while trying to make a get request to a public API on the internet using its own domain name (api.openweathermap.org).

Do you have a reproducer?

WebClient webClient = WebClient.create(vertx); webClient.get(80, getAbs(WEATHER_API_URL), "/data/2.5/find?q=" + city + "&APPID=" +APP_KEY).send(ar -> { if (ar.succeeded()) { LOG.info(ar.result().body()); } else { LOG.error(ar.cause().getCause()); Arrays.asList(ar.cause().getStackTrace()).forEach(stackTraceElement -> { LOG.error(stackTraceElement); }); } });

Using the ip adress is working :p
