bitcoin core – “Invalid address” when trying to solo mine with bfgminer

I’m planning to do solo mining.

i installed BitCoin Core Set up an incoming connection on my Windows box.

I wrote to the configuration file <BitCoinStore>/bitcoin.conf

server=1
rpcuser=myusername
rpcpassword=mypassword

Then I ran it on my Linux box.

bfgminer -o http://mywindowsaddress:8333 -u myusername -p mypassword --generate-to myincomingaddress

and got it

(2020-11-13 12:23:23) bfgminer: --generate-to: Invalid address

why? What is invalid?

Should I run? bitcoind So instead of a GUI on Windows?
