Trying to set up a tor relay (Middle/guard)

[cizo.tor]

Hi,
I am trying to setup a relay on a njalla vps but i a struggling !
I use Debian 12.

I have open my port 443 with sudo iptables -A INPUT -p tcp --dport 443 -j ACCEPT

In my torrc file i have change/unchecked :

ControlPort 9051
CookieAuthentication 1
ORPort 443
Nickname cizo.tor
ExitPolicy reject *:*

When i do sudo journalctl -u tor i get :

Jan 24 16:04:37 TorNode systemd[1]: Starting tor.service - Anonymizing overlay network for TCP (multi-instance-master)...
Jan 24 16:04:37 TorNode systemd[1]: Finished tor.service - Anonymizing overlay network for TCP (multi-instance-master).
Jan 24 16:07:34 TorNode systemd[1]: tor.service: Deactivated successfully.
Jan 24 16:07:34 TorNode systemd[1]: Stopped tor.service - Anonymizing overlay network for TCP (multi-instance-master).

When i do nyx i get :

Unable to connect to tor. Are you sure it's running?

Why ?
Thanks for your help

$ man tor:

   Nickname name
       Set the server’s nickname to 'name'. Nicknames must be between 1 and 19 characters inclusive, and must contain only the characters [a-zA-Z0-9]. If not set, Unnamed will be used. Relays can always
       be uniquely identified by their identity fingerprints.

Nickname cizo.tor

Remove . and try again?
