Hi @bkaindl , Again thanks for your support.
Finally, I succeeded in accessing my device. What I found, the newer BalenaOS >=v2.85 does not come in two flavors, i.e. development and production, instead, production is the default mode. I was using raspberrypi3-2.105.1+rev1-v14.2.0.img
and while using sudo balena scan
I saw it was in production mode. That’s why while configuring the image, I used
balena os configure ~/Downloads/raspberrypi3-2.105.1+rev1-v14.2.0.img --fleet myApp --dev
Also, I made a small adjustment in the original answer by @richbayliss from
Host *.balena
ProxyCommand proxytunnel -p vpn.<your openBalena domain>:3128 -d %h:22222 -F ~/.ssh/balena-ssh
ServerAliveInterval 30
To
Host *.balena
ProxyCommand proxytunnel -z -q -E -p tunnel.<your openBalena domain>:443 -d %h:22222 -F ~/.ssh/balena-ssh
ServerAliveInterval 30
Finally, could access my device by
$ ssh root@<full UUID>.balena
Again, thanks for your help. I really appreciate it.
