bastion key fails authentication

[Nishanth Shyamkumar]

Hi,

My bastion key is not passing authentication by the bastion host. This has happened before, and normally I run ‘configure_and_validate.ipynb’ to recreate keys and save the config.

However this time, even after validating successfully:

User: *****.edu bastion key is valid!
Configuration is valid and please save the config!

and saving the config,
I tried running some experiments, but it fails while logging in to the VMs.

I also tried running hello_fabric in Jupyter Hub and it fails while running the below commands:
`
for node in slice.get_nodes():
stdout, stderr = node.execute(‘echo Hello, FABRIC from node <code>hostname -s</code>’)
<code></code>`
Fails with:

AuthenticationException: Authentication failed.

I am running it on version 1.7.3 . Is there a fix for this?

Hi Nishanth. Bastion periodically “expire.” Could you go to Experiments -> Manage SSH Keys -> Bastion and check the expiration date? You may need to generate a new key pair. Please let me know if this appears to be the issue!

Hi,

I regenerated a fresh new keypair and it works now. Thanks.
