title: Connection refused trying to access REST endpoint on BigIP
body: <p>Attempting to connect to the REST endpoint of my BigIP:</p>
  
  <pre><code>curl https://10.1.0.69/mgmt/shared/appsvcs/info
  curl: (7) Failed to connect to 10.1.0.69 port 443: Connection refused 
  </code></pre>
  
  <p>I've seen some posts online stating that this could be due to <code>icrd</code> not being enabled, so to check the status:</p>
  
  <pre><code>admin@(ip-10-1-0-69)(cfg-sync Standalone)(Active)(/Common)(tmos)# show sys service icrd
  Couldn't find service: icrd
  </code></pre>
  
  <p>Next, I've tried enabling:</p>
  
  <pre><code>admin@(ip-10-1-0-69)(cfg-sync Standalone)(Active)(/Common)(tmos)# modify sys service icrd add
  Couldn't find service: icrd
  </code></pre>
  
  <p>My version info:</p>
  
  <pre><code>admin@(ip-10-1-0-69)(cfg-sync Standalone)(Active)(/Common)(tmos)# show /sys version

  <p>I've also seen some posts stating that I can do the following:</p>
  
  <pre><code>touch /etc/bigstart/scripts/scim
  bigstart add --default icrd
  bigstart enable icrd
  bigstart start icrd
  </code></pre>
  
  <p>However,</p>
  
  <pre><code>admin@(ip-10-1-0-69)(cfg-sync Standalone)(Active)(/Common)(tmos)# run /util bash
  [admin@ip-10-1-0-69:Active:Standalone] ~ # touch /etc/bigstart/scripts/scim
  [admin@ip-10-1-0-69:Active:Standalone] ~ # bigstart add --default icrd
  Couldn't find service: icrd
  </code></pre>
  
  <p>Also:</p>
  
  <pre><code>[admin@ip-10-1-0-69:Active:Standalone] ~ # bigstart status restjavad restnoded
  restjavad    run (pid 6549) 49 minutes
  restnoded    run (pid 5650) 49 minutes
  </code></pre>
  
  <p>Also, it appears the rest api is running but on port 8100:</p>
  
  <pre><code>[admin@ip-10-1-0-69:Active:Standalone] curl http://localhost:8100/mgmt/shared/appsvcs/info
  {"code":401,"message":"Authorization failed: no user authentication header or token detected. Uri:http://localhost:8100/mgmt/shared/appsvcs/info Referrer:Unknown Sender:Unknown","referer":"Unknown","restOperationId":6611305,"kind":":resterrorresponse"}
  </code></pre>
  
  <p>No ports are bound to 443:</p>
  
  <pre><code>[admin@ip-10-1-0-69:Active:Standalone] ~ # netstat -nalt | grep 443
  tcp        0      0 127.0.0.1:44352         127.0.0.1:6666          ESTABLISHED
  tcp        0      0 127.0.0.1:6666          127.0.0.1:44352         ESTABLISHED
  tcp6       0      0 :::8443                 :::*                    LISTEN
  </code></pre>
  
  <p>Any ideas?</p>
