Nice, thanks a lot for your help.

Yep, but this EINTR leads to the "Failed to parse JSON: 4" which was missing
in your logs, so I was confused. Then I saw `Connection to 172.30.31.233
closed by remote host.` in one of your latest logs and I've realized, that
you're not able to see those messages actually as those are only visible on
the serial console...
