It seems such a long time ago I battled with Sophos XG firewall (v15.x) to get Crashplan Central (Cloud Backup) to work through it (#1). Last month I upgraded to v16.x and hey, what do you know? A new problem with connection to Crashplan Central.

To make a long story short (read the forum posts), there's a bug (what else is new when it comes to Crashplan and XG) in v16 (including v16.0.1.1) that blocks the crashplan traffic. It's confirmed by Sophos KB (#2) and they say:
In certain situations traffic being passed through the XG firewall may appear be passed through the proxy even when no Web Policy is enabled within the relevant firewall rule and HTTP/HTTPS scanning is disabled."Both the KB and forumpost (#3) gives a workaround:
- Connect to the XG firewall via SSH and select option 4 (Device Console) from the menu
- run the below to disable this:
system application_classification microapp-discovery off - Restart Crashplan

PS! I have not checked, nor installed, v16.0.1.2 to confirm it's still there or not. Might do that soon, and update this post.
