Unable to set difficulty

I'm trying to connect to your pool from NiceHash rented scrypt miner and I get this error message

Your pool is shown as incompatible therefore we encourage you to contact pool operator to make sure that the pool is using minimal/starting pool share difficulty which is compatible with our service (and thus compatible with today's miners), please send them link to our FAQ on this topic: https://www.nicehash.com/index.jsp?p=faq#faqb3. Thank you!

I suggest that you remove the difficulty setting and see how that works for you. With rented hashing power you can't know the hardware, and so cannot know the optimal difficulty. If that brings no joy, then try setting a restart time. As for what value would be the best, I have no idea, and figuring it out will probably be problematic, given how hard it is to get hardware information on rented rigs.

Hi,

This is our work restart testing, which is know to cause problems with rented mining hardware. Try using a static work restart time with the r=# password argument, where # is the time the miner takes to recover from a work restart. That will resolve the error.

It works now with d=16384. I've noticed that initial diff now is 1024 insted of 16 which makes NiceHash happy.

Thank you
