Something broke after updating to Synology DSM 7.2

[revvr]

I have a Minecraft server on my Synology. When it updated to DSM 7.2 it looks like Docker was replaced with "Container Manager", which seems like the same thing as Docker. Anyway, after this update, I'm no longer able to connect to Minecraft. I only get an "Unable to connect to world" error.

Is this a known issue?

I've tried so many things to fix this, and I'm not having luck.

CanUSeeMe.org sees the port as open. My router has port forwarding on and it is configured just like how it was before this broke. I've tried connecting from a mobile network, a VPN, connecting to external IP address, internal IP address, and I get nothing.

Firewall on Synology is enabled and configured correctly, but no cigar. I tried disabling it, nothing.

I'm out of ideas. Wondering if anyone has had a similar experience or if anyone has other ideas that might help address this issue?

Thanks!
