Rebooting RPI4 cluster causes them to not come back online (Solved)

I have an application with 3 RPI4s and 1 RPI3 all on the 64-bit OS. I have been working on sending different container updates which generally work just fine but today I wanted to reboot all of my devices from the balenaCloud website and in doing so all of my devices went down and will not come back up. The weird thing is that they still seem to be active and I was even able to push an update to my release but the console still shows all of them as not available?

Solved, I had turned off VPN when it went down earlier. After turning it back on, nodes came back up.
