That is what I think because they are asking people on Reddit to test their server and post what model unit works on their server.
They also have an old list of supported miners on their Reddit but it's outdated and I don't see your unit there.


Why not switch to another pool instead if you want to run them together on a single pool?
ViaBTC would be a good option.
