Just received my A3, hooked it up and doesn't seem to be connecting. Tried to go to Antpool, but there is no longer a Siacoin Pool to choose from the dropdown list. Are these A3 miners being blocked?

Tried with miningpoolhub, but nothing seems to be happening.

The hardware version says "Socket connect failed: Connection refused"

Looked into some other pools, but not really sure how you would go about hooking up an ASIC to those. Would I just put it like this:

URL:  sia-asia1.nanopool.org:7777
worker: my sia wallet address?
password: x

Any insight would be appreciated.
