Unable to SSH into my Nodes

Hello,
I am facing a problem when I SSH to all nodes in my slice.

Hi Samia,

I verified all the VMs in your slice are accessible via SSH. The error you are noticing is probably because of expired bastion keys. Could you please try to re-execute the notebook: jupyter-examples-rel1.8.1/configure_and_validate/configure_and_validate.ipynb ?

This shall renew your bastion keys. If you are doing SSH from your laptop, please download the renewed bastion keys from /home/fabrirc/work/fabric_config directory after executing the notebook above to replace the keys in .ssh directory.

Please let me know if you run into any issues or have questions.

Thanks,

Komal

Thank you Komal, I am using the jupyter hub for now and it works.
