Here are the two diagnostic files from both nodes. I'm hoping you can find something from the data that explains why they cannot see each other. I really appreciate all your help. :) blacktower-tailscale-diag-20240224-004742.zip Domino-tailscale-diag-20240223-214925.zip

Firstly, thank you for your response. So, I tried to ping the other node using the Tailscale IP but it's not reachable, but I can ping the remote subnet router and other computers on the tailnet - except the other remote node. Both nodes can see other computers but not the other Unraid server.

I am trying to automate an rsync backup from my primary Unraid server to another unraid server that's in a remote location. They're both running the Tailscale plug-in, and I can access both Unraid servers from another computer on the TailNet. The problem I am having is when I'm on my Unraid server through the terminal, I cannot access or even ping the remote Unraid server. Both locations are running a subnet router, so when I'm on a Windows machine i can connect to each server with either a 192.168.x.x (remote) and 10.x.x.x (Home). I'm guessing the issue is with some sort of network/firewall issue that's preventing me from connecting between the 2 Unraid servers. I'm hoping someone can spot what I am doing wrong. Thank you very much for all your help.

Thanks for this awesome plug-in! I've been using Tailscale with dockers and as a lightweight VM for subnet routing. Right now, I'm just running the plug-in as a stand alone tailscale client and a separate VM for subnet routing. How robust would it be to just use this plug-in as a subnet router, too?

That's a good idea. Will try to do that. I will also post the full syslog, so hopefully that helps. Thank you!

My unraid still crashes to the point I can't depend on hosting some of my apps.

My Unraid server running on an HP gen8 microserver freezes up and stops responding randomlly around 1-2 months of being online. The last time this happened was in the beginning of October, so I finally setup my unraid to make a copy of the syslog in the flashdrive. It looks like my unraid froze on November 7 until I realized it was off today, November 9th. Can someone spot anything out of the ordinary with my syslog snippet? I would really appreciate it and it would help me figure out why this happens all the time.

I would be fine with just 2 drives, so I can keep the footprint small enough. I guess no more than the size of a QNAP TS-2xx or TS-4xx series. That 2-drive U-NAS looks like it'll be perfect! Thank you!

I was planning on building a miniature server for my in-laws that's in another state and I was looking for a computer that has a small footprint like a QNAP/synology 2-bay NAS. I was thinking that i could try a QNAP NAS to tinker with but I wanted to check if anyone else has other recommendations. Thanks!
