With absolute the same settings as before, I got this error:

Also pool hashrate is too small, even acceptes shares is small too (26 accepted shares after 7 minutes of mining), compairing to Gminer wich does 41 accepted shares after same 7 minutes of mining;

So?
really 7 minutes for a test? Dude you must test this for days.
Rigel has always better results than every other Nvidia miner in my case. An extreme case is conflux for me - gminer always 20% lower poolhashrate than the reported one.
Next thing are the fees - Rigel with low fees compared to gminer -> i mean what the fuck 5% fees in some cases?
