Today I ran a second test, using the RC5 release on my Start9 setup and I added another hashboard, factyory reset and ran AutoTune, when I was connected to the a officiel Sia Coin pool.
I found a post where Paul was testing on this setup
Pool URL:
stratum+tcp://sc.f2pool.com:7788

Worker:
26117c19ca3975b315d663dcbbc19cf9c07274f441689d4392ed380b2337589ef1aacfbdc93f.ObeliskSC1

Password:

And I did the same and the miner was hasning as expected on this pool climbing to about 950 Gh/s

I then updated to mine (solo) on my Start9 setup, but the same result as previous, Datum showed 1 client connected but no hashrate. I tested for about 1 hour with no changes.
On the Datum config I tried with and without Allow hasher time rolling for BLAKE2b jobs
