Hi Drew,
My mistake with the multiple server URLs came from the fact that I though the client should also know how to reach the storage server (which was actually caused by what I thought was causing the large uploads to the server failing).
In the meantime I found another forum thread that was specific to the problems with uploading large Artifact files to the server. It turns out that that was a bug in Server v2.3 that was resolved in Server 2.4.
I’ve updated our Server installation to Server 2.4 and those problems have disappeared. We’ve been able to perform multiple updates of our test devices and have now rolled out our first Menderized firmware for use with the devices that will be used in the field.
Here is a link to the forum thread about the large file upload issue:
