this is the error, I removed the stack part:

{

I tried running a new slice using new configuration in the JupyterHub, and it’s the same error:

“fabric@winter:work-33%$ ssh -i /home/fabric/work/fabric_config/slice_key -F /home/fabric/work/fabric_config/ssh_config ubuntu@<ip>
Warning: Permanently added ‘bastion.fabric-testbed.net’ (ED25519) to the list of known hosts.

kex_exchange_identification: Connection closed by remote host

I deleted all the keys and started the configuration notebook again, but nothing changed.

I even tried launching the nodes using the JupyterHub and it also did not work
