title: WildFly 20.0.0.Final - Unable to read the logging configuration from 'logging.properties' (java.net.UnknownHostException: usr)
body: <p>I upgrade from WildFly 19.x to 20.0.0.Final on 2020-06-08. My App was running fine locally with no issues &amp; I didn't really notice anything.</p>
  <p>I was away last weekend in the &quot;Wild Countryside&quot; with a very slow Internet connection. When I start WildFly 20 it starts with:</p>
  <pre><code>MacBook-Pro-2:bin NOTiFY$ ./standalone.sh -b 0.0.0.0 --server-config=standalone-full.xml
