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

I am trying to mine solo.

I have installed BitCoin Core on my Windows box, set up incoming connections

enter image description here

and wrote in config file <BitCoinStore>/bitcoin.conf

server=1
rpcuser=myusername
rpcpassword=mypassword

Then on Linux box I ran

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

and got

[2020-11-13 12:23:23] bfgminer: --generate-to: Invalid address

Why? What is invalid?

Should I run bitcoind instead of thus GUI on Windows?
