I'm having the same issue. Can someone please update?

[JimiPedros]

How can I get to nodes to communicate on the same chain

[LiuFangLu]

change if not self.valid_proof(last_block['proof'], block['proof'], last_block['previous_hash']) to if not self.valid_proof(last_block['proof'], block['proof'], block['previous_hash']), try again

Why was this reverted? And why was that a fix?
