WebHooks does not starts

Hi.
We are using the load_balancing setting for our GitLab cluster and set three nodes like this:

host: pgsql1
    port: 5000
load_balancing:
      hosts:
        - pgsql2
        - pgsql3

there are all works instead of WebHooks. All webhooks jobs are stucks in queue with error: database_replica_location.
