Trying to migrate a site from Craft 3 to Craft 4. Carefully followed the instructions to update my composer.json file to reflect the Craft 4 versions of Craft and all plugins. When I run composer update I get this error message: In CurlDownloader.php line 611:
The "https://composer.craftcms.com/providers/ccraftcms/cms.json" file could
not be downloaded (HTTP/2 404 )
Any wisdom on this would be greatly appreciated!
