Wrong port from older documentation. SSL hardware is now 443 (Cloud).

How to change depends on RPi library method (AKA programming language) chosen… But you can probably search through library files for 8441 and change it to 443.

For example in NodeJS client script

Or main library file

Yep… that’s an error :stuck_out_tongue: … I guess you could try Googling it as I don’t know what you did wrong.
