Hi,

I have been trying to send a directory mender artifact using the directory update-module. I am getting the following error on one of my RPi.

{"level":"info","message":"Running Mender client version: 3.5.2","timestamp":"2025-03-10T18:11:34+05:30"}

I have tried sending it multiple times, but the outcome is the same.

Following are my system specs:

  • CM Model: Raspberry Pi Compute Module 3 Plus Rev 1.0
  • Architecture: armv7l
  • OS: Raspbian GNU/Linux 10 (buster)
  • Kernel Version: 4.19.118-v7+

I can’t understand how to go around error. Any help is appreciated.
Thanks!

So I checked that the URL from which the mender client is trying to fetch the artifact is taking like 56s on an average to fetch data from the URL, which is probably resulting in a read connection timeout.

This brings up the question, How much is the timeout set in the mender client to fetch a package from the server?
And can that timeout be adjusted by some configuration?
