Repost from here: An error occured: read ECONNRESET - airmonitor build
It doesn’t seem like the problem is fixed as is written on the status page. Just wanted to make sure you are aware of it not being fixed.
Greetings and thanks for your efforts 
Edit: In the meantime for everybody having this problem, you can enforce a build that is locally emulated (i.e. definitely not running on arm03) as a workaround by running:
git push balena your-branch-name:balena-emulated
or if you are using the balena CLI to push your code:
balena push yourApplication --emulated
(I think this disables caching though 
)
