I am using bfgminer with Windows 10 for some gpu cards.  When I begin with opening the .bat file bfgminer says "Failed to resolve to host" and it will not begin running the miner.  What is wrong?

This is what bfgminer displays when I run the .bat file:


C:\Users\xxxxxxxx\Desktop\bfgminer>bfgminer-rpc.exe  -o http://654.3.2.1:5555  -u username -p password  --generate-to wallet address  -S opencl:auto
Failed to resolve host -u

C:\Users\xxxxxxxxxx\Desktop\bfgminer>pause
Press any key to continue . . .
