Error message: "Cannot connect to the balenaEngine daemon at unix:///var/run/balena-engine.sock. Is the balenaEngine daemon running?" when trying to execute any balena-engine command. Somebody fixed it? Balena daemon restarted by using "/etc/init.d/balena start" but the error keeps coming up.

 

Thank you.

Hello,

What PLC model do you have (e.g. AXC F 2152)

What firmware version is installed on the PLC (e.g. 2021.0 LTS)

How did you install balena-engine - using a script, or using the app in the PLCnext Store?
