Plasma bug - can't download new stuff

[Jim]

I've got Kubuntu 22.04 and I've found a bug.  In system settings I 
clicked appearance and tries to download a new global theme.  I clicked 
the Get New Global Themes button and got this error:

Loading of providers from file: 
https://autoconfig.kde.org/ocs/providers.xml failed

I also tried plasma style, and all the other options that had a Get New 
button.  Each time I clicked the Get New button I got the same error.  
Does anyone know how to fix this?  Thanks
