I'm trying to use the Quorum-examples/7nodes to test my contract. I followed the step on github and open a terminal to attach to node1. https://github.com/jpmorganchase/quorum-examples/tree/master/examples/7nodes
However, when I used Remix and choose Web3 Provider and enter http://localhost:22000 , but it doesn't work.
I do the same test on Web3.py and it can successfully connect.
