Hi,
We have intel NUC devices connected by an ethernet cable.
If one loses internet connection due to a network issue the device stays offline in resin.io.
We reproduced this by pulling the ethernet cable and then reinserting it after some time (several hours later).
Once we power cycle the device it connects just fine.
Shouldn’t devices (re)try to send updated after some time?
Hi. Can you try to reproduce this and when that happens try to fet the NM logs and send them over to us?
journalctl --no-pager -u NetworkManager
I tried it two times:

If you need more info, please let me know.
Hi,
We’re using Resin OS 2.12.7+rev2.
Thank you for confirming your os version. We worked on a similar reported issue these days. Would you be able to check a possible fix using a custom image?
Yes we can test using a custom image. Let us know where we can find it.
Hi. We will release a new OS version for the Intel NUC during this week. This new release will have some fixes with regards to DHCP timeout which we suspect will fix your problem also. So stay tuned for later this week on the new release
Good to know, thanks! We’ll let you know if this fixed the issue.
@floion We found these releases, but don’t see these releases in the dropdown in the “add device” screen in resin. When will these release be made public? Can we test them earlier?
they will be available in the following days; we discovered a bug while testing the version in staging so we need to do yet another release; stay tuned for deployment to production
We updated to Resin OS 2.13.5+rev1. Here are the logs:

These are the latest logs, this seems to work just fine. Thanks for the quick response!
