all Octavia LoadBalancer

Hi there, I recently deployed a load balancer on our openstack private cloud. I used this manual - https://docs.openstack.org/octavia/latest/user/guides/basic-cookbook.html to create the load balancer. However, after creating and trying to access it, it returns an error message saying "No server is available to handle this request". Also on the dashboard, "Operating status" shows offline but "provisioning status" shows active. I have two web applications as members of the load balancer and I can individually access those web applications. Could someone please point me in the right direction? Thanks.
