MRR>xmr.nanopool.org error

I have no problems connecting to support xmr through MRR.
Yes, there is no problem, just when such errors occur, the statistics are reset to 0 and the new one !!!!! And let's essentially !!!
Please try adding the --pool_broken_rpc option to your command line arguments for the miner. This should fix the issue you are seeing with nanopool.
If you are running in windows, you can do this by editing the .bat file that you use to start the miner.
