Hello,
I am not able to use the --lodiff option.
When the option is enabled, I am not able to connect to the stratum server as shown on the following picture:

When the option is disabled, the miner is working just fine:

I also tried to mine on CWI pool using ccminer instead of cwi miner:
- lodiff port 2000 can't connect
- hidiff port 6000 work perfectly fine
Do you know what can block me using the lodiff port?
I am running 4 x 1070s and I don't use any flags. It does mine on 6000 do takes longer to submit a share but the share has more value compared to ones you would submit using a lo diff port.
