I had setup a digital ocean running Debian 11 bullseye. Installed splunk community and have a few cron jobs to get some data. Mostly monitoring some stuff of mine. I am moving from a on prem install which been going on for over a year no issue.
So, I set my firewall to allow no incoming since I have zerotier running and everything works fine for a week. Then my dashboard is unreachable. Nothing in the logs… I cant hit the box via ZT so I get in via DO CLI and it has the ZT IP. I enable the port 22 to the public FW and I connect for troubleshooting. I reinstalled ZT and confirmed everything I can and still cant communicate over zerotier. Checked the linux firewall and all looks good.
Been using ZT for years and never had this issue come up. This is really a basic setup nothing strange.
I have 4+ devices and the other 3 can ping each other but none this DO Server.

I changed the port to 9992 and 9995 with the same result and then changed it back to default. What else should I try and or do to fix this issue?
Edit: I added a Lightsail instance and my MacMini. The MacMini nor the raspi can connect to any DO or Lightsail but my windows can. Neither cloud servers can reach the mac or raspi but my other devices have no problem.
Example connecting to one of my pi from the server but my win to server works.
