SSH Connection Refused After OTA Update On Jetson AGX Xavier

Hi all,

After updating my Jetson AGX Xavier to Jetson Linux 35.6.0 following the Over-The-Air Update guide, I ran into an issue.

Post sudo reboot, I confirmed the device was reachable by ping, but SSH attempts using the old credentials (ssh <username>@<ip>) returned:

ssh: connect to host <ip> port 22: Connection refused

Is there a way to restore SSH access remotely without physical intervention and without using USB? I specifically chose OTA over SDK Manager because of this. I only have VPN network access and no physical access.

Any help would be greatly appreciated!

hello peter.hofinger,

it may due to remote host identification has changed,
please try below… $ ssh-keygen -f "/home/<account>/.ssh/known_hosts" -R "IP-Address"
