Host Refused connection - Passing through F5

Hi,

first of did you set up ssl interception?

if yes, you need a ssl client profil and ssl server profil (if your backend listen in ssl/TLS port). you need also http profil in this case.

If no, you don't need HTTP profil, ssl server or client profil.

Last point if you have a cluster check that your floating IP have access to your backend, because monitoring is done with self IP and you can have a green monitoring and can't access to your service if you don't open flow with floating IP as source.

regards
