I am unable to download images to my jetson nano device due to persistent errors of the form: Failed to download image (id removed for posting purposes) due to ‘connect ECONNREFUSED /var/run/balena-engine.sock’ It seems to always occur after about 6 minutes of downloading, and has held us up for a…

I had tried with and without delta updates - same issue. It would abort the downloads with the ECONNREFUSED message after about 6 minutes. I just went and quickly picked up a UHS-I card, and the problem has been solved! Works like a charm. Since I tried with two separate slower (class 4) cards p…

Hi @drcnyc – thanks for your post. Can I ask a couple things: Can you run Diagnostics on your device and see if there are any problems reported? Can you let me know the size of your image, and what kind of network connection you have? All the best, Hugh

Assuming for the moment that’s true, can you try disabling Delta Updates under “Devi…

Glad you sorted it. We always recommend to use the best quality SD cards available on the market both for performance and resilience. What OS version is this? There was a bug in some OS versions where the watchdog would kill balena-engine if it took too long to update and that consistent 6-minute ti…

That would definitely do it too. It is running 2.51.1+rev1 - let me know if that version would have the bug.

I don’t believe that is it, that issue should have been fixed around 2.41.0

I think I am seeing this on a Pi0 with balenaOS 2.54.2+rev1. Are there any definitions I can use to relax the watchdog timing?
