Hi!
I’ve been working through the Mender tutorials and am trying to perform an OTA update of our application software through hosted.mender.io as a simple proof of concept. I have installed mender-client on a local VM and have been able to successfully update the application binary on the VM to a newer version by creating a new release using mender-artifact and initiating the deployment through the hosted Mender frontend. However, I’ve seen the deployment occasionally fail for reasons that are unclear to me (failure logs copied below). When I’ve seen this failure, I’ve been able to recreate the deployment exactly and have it go through successfully so I’m not quite sure what the source of the problem is. If there is more context I can provide that will help diagnose this let me know.
