Unable to access Hosted Websites, browsers show a ‘Service Unavailable’ error.

The Service Unavailable error message occurs if the backend service is not up and running or AccessTier/Connector is unable to reach the backend service.
1.- Run a ‘Test Connection’ from Banyan Command Center.
Private Access > Hosted Websites > Click the name of the Hosted Website > Click the button in the top right to run the test.

Test will show if there are any issues reaching the backend service.
E.g.:

2.- Take a capture on the Access tier (or Connector).
** You will need to know the real IP of the website you're trying to reach (backend service).
** Open a CLI to the Access Tier and get ready to start the packet capture with the command "sudo tcpdump -i any -w host ".
E.g:
sudo tcpdump -i any -w capturesw.pcap host 172.31.14.131
** Attempt to access the hosted site.
** Let this complete and fail.
** Stop the capture (Control+C).
** Download and analyze the capture.
3.- Make sure there are no security groups, firewall rules, etc blocking communication between AccessTier/Connector and backend service on desired port.
