Brief description of the problem

There is a certificate problem with the Duplicati Rock-On performing backups to BackBlaze. When I tried to check whether there was an updated image I got another certificate issue. I don’t know if it is the same root cause.

Detailed step by step instructions to reproduce the problem

Go to Rock-Ons tab. Click Updates.

Hi @jmangan, and welcome back!

@phillxnet wrote a brief answer to a similar post just a few days ago so that will be your best resource:

In short, this is a bug related to the now very old age of Rockstor v3. Although the post linked does point to a workaround, it is strongly recommended to consider moving to Rockstor v4 as it includes many many improvements across the board especially on the core Btrfs stack.

Hope this helps,


@Flox, thanks for that. I hadn’t seen an announcement that V4 was now release-ready. I’ll have a look at that.

Thanks again.
