title: jfrog artifactory could not validate router error
body: <p>When I download, unpack and launch <code>artifactory.sh</code> I see the following error</p>
  
  <pre><code>2020-02-26T21:32:50.496Z [jfac ] [ERROR] [c1b4de79a3f11666] [.j.a.s.s.r.JoinServiceImpl:253] [http-nio-8040-exec-1] - Could not validate router Check-url: http://XXXXXX:8082/router/api/v1/system/ping
  </code></pre>
  
  <p>And then</p>
  
  <pre><code>2020-02-26T21:32:55.636Z [jfac ] [WARN ] [67b9d42698f5614c] [o.j.c.ExecutionUtils:141      ] [pool-6-thread-2     ] - Retry 20 Elapsed 9.04 secs failed: Registration with router on URL http://localhost:8046 failed with error: UNAVAILABLE: io exception. Trying again
  </code></pre>
  
  <p>I realize I'm missing something obvious but couldn't figure it out yet. Any suggestions? Thanks.</p>
