Hello, I've just installed stein on centos 7 with octavia.
I created the amphora image based on centosĀ  , but when a load balance is created the amphora instance does note have any proces on port 9443 and the worker reports:

2019-12-10 08:40:14.456 3710 WARNING octavia.amphorae.drivers.haproxy.rest_api_driver [-] Could not connect to instance. Retrying.: ConnectTimeout: HTTPSConnectionPool(host='10.102.143.94', port=9443): Max retries exceeded with url: // (Caused by ConnectTimeoutError(<urllib3.connection.VerifiedHTTPSConnection object at 0x7f4a04de0d10>, 'Connection to 10.102.143.94 timed out. (connect timeout=10.0)'))

Network connectivity and security groups are ok.
I connected on the instance via ssh and I cannot see any listening 9443 port.
Anyone can help me, please ?
Ignazio
