Removed a few routes and now no devices can get a valid ip address

I removed two routes and then everything died. Trying to get a single machine on the vpn working with no success. I have upgraded zerotier to the latest on a ubuntu instance. I have removed the security tokens, left and rejoined.

I keep getting an ip address with a wrong subnet

15: ztmjfhd6iq: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 2800 qdisc fq_codel state UNKNOWN group default qlen 1000
link/ether 0e:1d:04:38:aa:47 brd ff:ff:ff:ff:ff:ff
inet 172.24.109.248/0 brd 255.255.255.255 scope global ztmjfhd6iq
valid_lft forever preferred_lft forever
inet6 fe80::c1d:4ff:fe38:aa47/64 scope link
valid_lft forever preferred_lft forever

notice the /0

I am having similar issue on many other nodes. Any suggestions, I need to get these machines talking again.

You deleted the LAN route from your network that matches your auto assignment pool. Given that your auto assign pool is 172.24.0.1 to 172.24.255.254, your LAN route should be 172.24.0.0/16. Leave the (Via) input blank. A LAN route matching your auto assign pool must be present for anything to work.

Well that explains why nothing works.

I added it back. What should I do on the various nodes to get that to fix to apply? As things are still not able to reach each other.

fwiw I was sort of expecting the subnet mask thing to fix itself

19: ztmjfhd6iq: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 2800 qdisc fq_codel state UNKNOWN group default qlen 1000
link/ether 0e:1d:04:38:aa:47 brd ff:ff:ff:ff:ff:ff
inet 172.24.109.248/0 brd 255.255.255.255 scope global ztmjfhd6iq
valid_lft forever preferred_lft forever
inet6 fe80::c1d:4ff:fe38:aa47/64 scope link
valid_lft forever preferred_lft forever

just wait a few minutes and everything should figure it out. Or if you wish, you can leave & rejoin the network on those machines

Thanks I will just wait.

Thanks for the prompt response, definitely a life saver as I had 5K users screaming at me.

Everything is back up and working now.

Thanks again.
