I have problem.
When node is starting following the instruction I got mesage-miner key import failed.What is problem?Maybe with sertificate?
I had similar problem : the miner key generated by the windows wallet seems too long with unusual caracters ...
I have started to mine with the pool above.
I actually had the same problem in the first time.
Be careful with how you copy the data in/out in the CMD - re-check with Notepad++ if there are no unnecessary spaces or anything.
