+!!! warning "Important Note re hostname validation"
 
+    (**Updated 10 June 2018**) : In SABnzbd [2.3.3](https://sabnzbd.org/wiki/extra/hostname-check.html), hostname verification was added as a mandatory check. SABnzbd will refuse inbound connections which weren't addressed to its own (_initially, autodetected_) hostname. This presents a problem within Docker Swarm, where container hostnames are random and disposable.
+
+    You'll need to edit sabnzbd.ini (_only created after your first launch_), and **replace** the value in ```host_whitelist``` configuration (_it's comma-separated_) with the name of your service within the swarm definition, as well as your FQDN as accessed via traefik.
+
+    For example, mine simply reads ```host_whitelist = sabnzbd.funkypenguin.co.nz, sabnzbd```
