I have just begun an On-Demand course for Elasticsearch Engineer I. I have setup the lab environment correctly, I believe, when for the first lab in the course, I get this error message in Strigo when entering "./load_lab.sh 1":
curl: (52) Empty reply from server
Some progress. After starting Strigo a few more times, I finally paused it. Then I came back to it after 5-10 minutes and resumed. Now I can load the lab and ssh to the three machines.
I think I am all set now. The browser ended up with a hodge podge of working and not-working URLs from Strigo. I cleared the browser cache and tried the latest URL and it worked.
