I can't upload files to Servers folder as MC user

No matter how hard I try, when I use FileZilla to upload a server folder as the default MC account, it never works. It just says “failed” or “Denied”

Is there a way to fix this?

Thanks!

I would check your permissions to the server directory. You should be logging in to the UI as MC, not root. If you have created the server as root you’ll need to change the permissions using the CLI.

The server was created under the MC user, what command would I need to change the mc users permissions?
