title: Google Captcha ERROR for site owner: Invalid domain for site key on loadbalancer and unable to send out email
body: <p>I got some problems that I have been stuck with for almost 1 week now. it's about this error google captcha site key</p>
  <p>and cant send out emails from the load balancer.</p>
  <p>the network topology is this the 3 webserver is on 1 load balancer IP address...
  when I'm using the load balancer as an IP address at my DNS the error came out saying this</p>
  <p>Google Captcha ERROR for site owner: Invalid domain for site key</p>
  <p>and cant send out an email from the load balancer IP saying this error</p>
  <p>{&quot;status&quot;:&quot;error&quot;,&quot;time&quot;:0.0,&quot;flags&quot;:{},&quot;data&quot;:{&quot;code&quot;:&quot;UnauthenticatedFromAddress&quot;,&quot;message&quot;:&quot;The From address is not authorised to send mail from this server&quot;}}</p>
  <p>what should I do guys tell me is this something with the SSL? or the firewall rule on the load balancer?</p>
  <p>I'm so fascinated that I know this technology becos my business is cloud-based I can't afford downtime it costs me a lot and losing clients.</p>
  <p>I'm willing to give someone who can solve this a gift from my heart with some dollar donation for helping me.</p>
