I am having very similar error for running btcpool as well

same issue

BTCAgent can only be connected to the stratum server of the BTCPool project, and its extra nonce2's size will be 8 bytes.

It doesn't make sense to connect to other pool's server. Because they do not support the BTCAgent protocol so no share can be submited.
