I tried using Minera with
www.miningrigrentals.comdoesn't matter what i do, it just won't connect,
if i put the address in first, it's replaces it by a number like 6da23413, then spits out invalid url.
if i put it as a fail over and choses it after, on the top line ( putty and screen-r ) where it says connected, it will put a bunch of ascii charater and fail to connect.
and even more weird.
if i leave in in the pool selection somewhere
have betarigs in primary
have another pool like Coinmine.pw in failover
it will skip the betarigs since no rental is active
connect to coinmine and won't submit anyshares.
but if i remove miningrigs rental from the list and reboot
all is fine. just in case you want to reproduce this or investigate, the mininrigrental server i;m using is: us-east01.miningrigrentals.com
good luck
