This is a fresh installation, no configuration changes apart from changes documented to run mailcow behind a reverse proxy.

You messed up the file permissions of the mailcow base directory.

Please read the docs carefully. Clone the script as root, check the umask etc.

Do not copy the directory without carrying the file permissions.

After adjusting the directory permissions, it has worked as expected.

Thanks.
