SOLVED :
open the rpc 8888 port ( windows firewall )
- start gkr with : gkr --rpc --mine "your_wallet" --miningthreads "your_threads"
- run Start_Mining.bat file (wait fro DAG file) --- done!
hi i tried this : start gkr with : gkr --rpc --mine "0x..........." --minerthreads "4"
then a heap of lists of goroutines then it exits.
