I have topology looks like
User -> DNS -> Haproxy (google compute) -> Google Load Balancer -> Instance Group
The traffics is comming to haproxy and mapping to 3 load balancers.
I get a lot of responses with
-1 code on haproxy, for example
0/0/1/-1/287 -1 0/0/6/-1/109 -1 0/0/2/-1/233 -1
I read from haproxy docs 8.5 section, the docs said :
I want to know why so many get timeout server, because instance group under load balancer is fine. How can I trace them because all request with that response not comming to each instance on instance group?
