Hi everybody, I’m having an issue logging into the notebook.
Everything was working fine up up until the end of lesson 1. I was able to get everything setup and running; was at the point where we were unzipping the the cats and dogs files in terminal. However, somewhere during this point, the tmux window in terminal froze and I had to force close the window. I lost my session and wasn’t sure what to do, so I decided to close aws using the amazon web browser: Instances => instance state => stop, instead of using terminal. Now, when I try to log into the notebook: source aws-alias.sh => aws-start, I get the following error:
~ $ aws-start
An error occurred (InvalidParameterCombination) when calling the StartInstances operation: No instances specified
~ $ aws-ssh
ssh: Could not resolve hostname None: nodename nor servname provided, or not known
Any suggestions on how to get the notebook back up and running?
