Sophos UTM blocking Synology Drive file share links?

Hi folks

I have an interesting problem.

I have a Synology 1517+ NAS sitting behind a SophosUTM appliance.

The UTM has correct firewall configuration to let through key NAS services - admin access, file access, etc. Normally I can access Synology's Drive service (equivalent to Google Drive but running on my own server) outside my home network with no issues.

The problem happens when I want to share files from Synology Drive. The file share creates a link to the file as seen in the screenshot below. The problem is that this link cannot be accessed outside my LAN. Access outside my LAN throws a "ERR_CONNECTION_RESET" error.

I have checked ports used by Synology Drive and it's all the same ones I already have opened. Given the issue only happens when accessing outside my LAN, I place this firmly at the feet of Sophos.

Any advice much appreciated.
