I can't start 2 nodes in multi mode

[3qicey]

Good evening.
Initially, we collected everything on a test stand in single mode. Everything worked.

The node characteristics are as follows:
1 disk for the OS and 9 disks formatted in XFS, as specified in the instructions on the website.
The only issue is that the RUSTFS_VOLUMES= line in the /etc/default/rustfs configuration file did not start as described in the guide (RUSTFS_VOLUMES="/data/rustfs{0...3}") .It only worked after specifying the variables in a different way :(RUSTFS_VOLUMES="/data/rustfs0 /data/rustfs1 /data/rustfs2 "
We brought in the second node. We configured it according to the article. In the host file, I marked the external IPs as follows:185.91.12.1 node1 185.91.12.2 node2. On the first node, the settings in the config were changed according to the article, but nothing started (RUSTFS_VOLUMES="http://node{1...4}:9000/data/rustfs{0...3}")
Is there really no error here?
Do I need a \ in sudo tee /etc/systemd/system/rustfs.service in the line: ExecStart=/usr/local/bin/rustfs $RUSTFS_VOLUMES
And does the system work via an external IP?
What happens when we bind a domain name to an IP with an SSL server?
