Hi there,
I have the same issue as others that might need a tweak from you. I'm copying and pasting my API key (I have no ticker name for some reason, even though I've claimed my address(es) ).

I've set up pooltool.json correctly, I believe
{ "api_key": "REDACTED", "pools": [ { "name": "VSPBM", "pool_id": "0e430a017eb4b13826f48bee4e95ddf39d4187ec7467e8e5363bdfbb", "host" : "192.168.0.124", "port": 6010 } ]
