CLNRest: certificate verify failed: unable to get local issuer certificate (_ssl.c:1007) about lightning HOT 3 OPEN

Maybe you can try to disable server certificate verification with the following line

http_session.verify = False

In the example of the documentation it is set to True.

I think you can also set it to the full path to your certificate (/path-to/ca.pem).

You can find more information here:

https://python-socketio.readthedocs.io/en/latest/client.html

If you want to give a try to a JS client you can check the first section in this live session we did in September:

The change to False of the .verify flag worked. After that I realized my virtual environment was missing websocket-client.
Now it works.

I also tried specifying the full path to ca.pem but that caused the server to refuse the connection:

HTTPSConnectionPool(host='10.0.0.25', port=3010): Max retries exceeded with url: /socket.io/?transport=polling&EIO=4&t=1702596534.9846961 (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f4f52b0ba60>: Failed to establish a new connection: [Errno 111] Connection refused'))

Once removed the ca.pem part, it worked again.

Thanks!!

Thanks! I'll give it a try.
