getting not resolved host error only in linux

Bug Report

Versions

• Driver: Postgres
• Database: Postgres & yugabyte
• Java: all testet
• OS: only in Linux

Current Behavior

I am using r2dbc with akka. After akka switched to the 1.0.1.RELEASE

i have the strange behavior that i can connect to my databases with mac os arm64 and amd64 with no errors but on linux system even when building in the nativ environment i always get

reactor.core.Exceptions$ErrorCallbackNotImplemented: io.r2dbc.postgresql.PostgresqlConnectionFactory$PostgresConnectionException: [08003] Cannot connect to myhostname/:5433

the host can reached with curl -v and resolved -> i can reproduce the error in every environment only on linux the hosts are not resolved

I am using scala. Have used all Scala Version to test but its the same result.

Steps to reproduce

val config = PostgresqlConnectionConfiguration
  .builder()
  .errorResponseLogLevel(io.r2dbc.postgresql.util.LogLevel.DEBUG)
  .host("myhost.x")
  .port(5433)
  .database("mydatabase")
  .username("username")
  .password("secretpassword")
  .build()

val connectionFactory: ConnectionFactory = new PostgresqlConnectionFactory(config)
val connection = connectionFactory.create()

val mono: Mono[Connection] = Flux.from(connection).next()

mono.flatMapMany(connection => {
  println("Connection established")
  connection.createStatement("INSERT INTO person (id, first_name, last_name) VALUES ($1, $2, $3)")
    .bind("$1", 1)
    .bind("$2", "Walter")
    .bind("$3", "White")
    .execute()
}).flatMap(result => {
    println("Statement executed")
    result.getRowsUpdated
    }).subscribe(rowsUpdated => {
    println("Inserted " + rowsUpdated + " row(s)")

})

Expected behavior/code

Connection on linux hosts should work.

Possible Solution

I don`t know...

There were some javalibs overwriting my scala libs
