Hi,
Earlier versions did not check license key after you updated it.
This issue could be related to the older version of system software (PHP, curl) installed at your hosting server:

Try input into browser this URL:
https://www.role-editor.com/update?action=get_metadata&slug=user-role-editor-pro&license_key=your-license-key-here
Does it work without error?
URE just calls wp_remote_get() with this URL. A problem with SSL connection occurs at PHP or even deeper system level.
