I think I done something wrong 😞

AVERTISSEMENT io.netty.bootstrap.ServerBootstrap$ServerBootstrapAcceptor forceClose Failed to register an accepted channel: [id: 0x01a0436e, L:0.0.0.0/0.0.0.0:8080]
java.lang.IllegalStateException
	at io.vertx.core.net.impl.VertxEventLoopGroup.next(VertxEventLoopGroup.java:47)

Maybe try a different port, sometimes the old port stays bound when improperly terminated... but then this is already off topic for #coroutines, try #vertx... or #server

thanks
