using the flow "Goodwe SEMS portal Solar panel data to Node-RED" to get data from my GOODWE panels.  
Updated the flow to include my account and and password and the psid (which I got from the portal by logging in successfully)  
Get a "Connection Refused" error from the 'Request Token' node.

Accessing the URL directly gives an explanation of the error (but not a solution)

GoodWe migrated to Version 2 of the SEMS portal about 18 months ago and changed a lot of the APIs - i never bothered migrating my old code as i talk to my inverters directly through Modbus.

You should be able to do this with a standard HTTPS call and not worry about the custom nodes - it is not too hard to work out what each of the fields returned are once you break them out as an object and send them to the debug window
