Compute server down after ec2 restart + bootstrap file issues

I had set up an AWS EC2 Rhino.Compute server which was working fine throughout testing. Before deploying my website, I wanted to reset an AWS access key that could’ve been compromised so I stopped the ec2 instance, attached a new key and restarted. I’m nearly certain that’s the only change I made that affected the compute server. Afterwards, my calls to the server would cause timeouts. I checked that the server was running (pinging activechildren and healthcheck also worked). The logs on the server showed this error:

I tried updating rhino on my VM according to the guide and that didn’t work. It prompts you for an email address and when I put mine in it raised this error:

Then because I wanted to speed things along and thought that maybe I managed to mess something up, I started a new instance from scratch. Following the guide, I ran the first bootstrap script and got the following error:

As always, any help would be much appreciated!

Hmm… You said you started a new instance from scratch and then ran the bootstrap script and it fails installing Rhino? That’s from a brand new EC2 instance? The download URL that’s used in the bootstrap script should be https://www.rhino3d.com/download/rhino-for-windows/7/latest/direct?email=EnterYourEmailHere You need to replace the last part that says EnterYourEmailHere with a valid email address. If you copy that URL into a browser and replace the last part with a valid email, does your browser download the file?

I should’ve relayed this sooner because I just saw someone link to this post with the same issue. I’m fairly sure my issue was that I had either a trailing or a leading space in the API key I had copy-pasted. The script didn’t raise any kind of error when I inputted the key, but I would get the errors above. After I generated a new key and more carefully copied it, the bootstrap scripts ran without a problem.
