Cannot SSH to VMs on newy-w2.fabric-testbed.net

Due to an issue just discovered in newy-w2, we had to reboot the server. Please try your ssh in about 30 minutes. It should be up by then.

Hello! I am new to Fabric and I have been getting the same error Fraida got. I created the bastion SSH keys using the portal and used the configure file in JupytetHub to configure the sliver keys and the SSH config file. A coworker of mine has also been facing the same issue. Where could we be going wrong?

Hello! I have followed that notebook and created a slice! moreover, I also added the public key to the node in the slice using the ‘Add/Remove SSh keys’ notebook. On a side note, I am using the sliver keys generated by jupyterhub.

Hello! Yes I am still facing the same issue

I did what you suggested and I am still getting the same error from the jupyterhub terminal as well as my local machine terminal.

okay I will try to do that. I just want to confirm that after creating a slice and adding a node to it I will also need to add the public slice_key to that node using the “add/remove ssh keys” notebook right? and then I will be able to ssh into the vm
