I have FlexRig rented but leaserig is not showing accepted shares and my pool is showing very low share amount. I don't know what could be the problem 
Tried also mining on CoinKing but no accepted shares.
Edit: Tried another pool and seems to be working.

I am sorry to hear you experienced issues while renting FlexRig! I have been trying to reproduce the issues you mentioned myself, but thus far have been unable to do so. I have noticed CoinKing takes about 15 minutes before the correct hashrate is shown for both individual workers, and overall hashrate. Would you mind sharing which pools you were experiencing issues with?
I have been experiencing stability issues with LRP provided by LeaseRig, and have stopped using the system as a result. They are in Alpha testing for a new system, but until then I am using direct connect. I am not sure if this is the reason you were experiencing issues.
Were you at all unsatisfied with your experience renting from me overall? If so, please PM me!
In the future please contact me via PM for support during an active lease as I get email alerts for new PM's and will respond very quickly.
