I am currently facing some problems with Netfoundry.
In particular, I keep getting these warning/error messages when I check “systemctl status ziti-edge-tunnel.service”:
Also, it seems that the host I try to reach through NetFoundry, loses its connectivity every 20/30 mins, so I am forced to do “systemctl restart ziti-edge-tunnel.service” by hand every time.
There is a known bug in the version v0.21.6-local for the exact behavior you are observing in your setup where tunneler is not able to connect the edge routers.
Can you please downgrade the version to v0.21.5-local & check the working status.
Command to be used → sudo apt install ziti-edge-tunnel=0.21.5
