Odd IP for one of my clients, not my ISP

I’m using the docker for Unraid, after the latest update (1.12.1) that machine isn’t connectable (another one, same OS and version is)… but when I look on the network status page the reported IP is hosted by Vultr (I don’t use them) and when I Google it, a result on the Zerotier Reddit is the first result (https://www.reddit.com/r/zerotier/comments/tdnxfq/stuck_on_requesting_configuration)

How can I troubleshoot this?
