SMA Solar integration setup issue

I seem unable to get this integration to get past the authorization step!
I have just installed the latest HA on a RPi 5 and it working and I have been able to add other integrations without difficulty.
I successfully found and added the SMA Solar integration
I got the popup to connect to the Sunny Webbox and it refuses both the user and installer authentication with and without SSL boxes checked. The Sunny Webbox has static IP
Has anyone encountered this and if so is there a work around?
Thanks

If you have a supported inverter then make sure you use the following integration configuration options:

Uses SSL certificate → true (check the box)
Verify SSL certificate → false (uncheck the box)

Note, you should be connecting to the inverter, not the Webbox - that is not supported.

Ok thank you very much!
I guess I will have to go down the RS-485 rabbit hole and figure out how to get this up and monitored
Appreciate the help and link
