Is there a good SpaceRex tutorial specifically teaching how to use Tailscale for Snapshot Replication between two NAS in separate locations? I’ve heard Will mention it in other videos, but I couldn’t find a video specifically about Tailscale and Snapshot Replication.

I am using the ‘Enable Outbound Connections’ script and I can access DSM via Tailscale. TUN Mode is enabled on both, so that is not the issue. I am not using a firewall on either NAS.

No matter what I always receive the error ‘The destination server failed to connect to this server.’ I even get this error when manually entering the Tailscale addresses in the advanced configuration menu.

I’m out of ideas. I would be very grateful for any advice or a link to a tutorial.

Thank you!
