I just set up an infra Vault on AWS with an ALB (internal) front end.
I noticed that when I used the route “/sys/health/?standbyok=true” the ALB traffic is redirected on the vault “master” node as well as on the vault “standby” nodes.
But my Vault cluster doesn’t answer anymore if my https request is forwarded to one of the standby nodes. But isn’t it supposed to have a forwarding from the standby nodes to the master node ?
In the meantime I modified the ALB healtcheck to use the “/sys/health” route so that only the master node returns a 200 and my cluster responds perfectly.
Do I have a problem in my configuration ? or is this a normal behavior ?
