Hi, all,

I am trying to create a load balancer in octavia. The amphora can be booted
successfully, and can be reached via icmp. However, octavia fails to plug
vip to the amphora through the amphora client api and returns 500 status
code, causing some errors as follows.

                                           |__Flow

To fix the problem, I log in the amphora and find that there is one http
server process is listening on port 9443, so I think the amphora api
services is active. But do not know how to further investigate what error
happens inside the amphora api service and solve it? Look forward to your
valuable comments.

Best regards,
Yipei
