connect to cluster - key not accessible

Hello,

From the error message, it looks like either your pluster ssh or pcluster dcv-connect command is unable to find the .pem identity file that you have created as part of the Create a SSH key section.

If the .pem file is in a different location, you can provide the full path of the .pem with the -i flag as shown below.

pcluster ssh --cluster-name cfd -i /path/to/KEY_NAME.pem

(OR)

pcluster dcv-connect --cluster-name cfd --key-path /path/to/KEY_NAME.pem --show-url

If you are still facing issues after making sure that the file is present, you can open a issue on aws/aws-parallelcluster github project with detailed steps to reproduce or open a support case for further investigation.
