The Snapshot destination folder is not writable

After I move my website to new Cloudways app (same server just different app or different public_html folder) , Snapshot giving me the following errors:
ERROR: The Snapshot destination folder is not writable
ERROR: The Snapshot restore folder is not writable
ERROR: The Snapshot destination folder is not writable
ERROR: The Snapshot destination folder is not writable
ERROR: The Snapshot locks folder is not writable

I've read this topic and others too, but not worked, except if I set the permission to 777. But I dont want to keep as 777 file permission, because it's not safe.

can you please check what's wrong with my server configuration or permission?
