HAProxy Working But Not Talking to Rev

503 means HAProxy is working but Rev machines aren't talking to haproxy.

• First verify all Vbrick services are running, if not restart them
• Check if Rev machines give you a 404 if you go directly to their hostname. If so then they're working but haproxy may not have the right info (i.e. wrong hostname or wrong IP address).
• Try running Rev in console mode and note any errors (NOTE: Stop the Rev Runtime services before doing this)
• If you get RabbitMQ related issues then shut down the RabbitMQ service on ALL servers, wait 10-15 sec then startup again (follow Rabbit Restart Procedure)
• If Rev works in console mode but not as service then make sure windows account used for Rev Service has appropriate access rights (i.e. Local Administrator)
