We have configured using IP in allowedclients section of dispatcher before and it worked fine when dispatcher flush is trying to talk.
Now planning to move to AWS as part of that we are trying to update with AWS A record like "a.b.cloud.com" instead of IP but getting forbidden error [1] when trying to do dispatcher flush communication from author/publish.
So trying to see if this could be allowing only IP or if we need to configure in a different way to allow A record like "a.b.cloud.com" ?
