no netconf response from switch

[rlatndls0211]

I'm trying to start a session using an SSH client and send a netconf command to the switch.
The request was sent successfully, but there is no response from the switch.

[root@localhost ~]# sshpass -p **** ssh -s admin@[ip] -p 830 netconf

This stops here and ends with an idle timeout. Switch model is Cisco Nexux NX api 9100

Not super familiar with this platform, but have you already tried these troubleshooting steps ?
