SuiteCRM states compatibility with PHP 7.3, 7.4 and 8.0, however API v8 in public/legacy is still compatible only with 7.3 and 7.4 because of SugarCRM. It is not possible to parse private key because of their dependencies and it always ends up in 500.
Proposed fixes and/or additions
Split UI and API in compatibility matrix until rewrite in Symfony is complete
