Trying to pass the "Enthusiast" level, I have an IPv6 accessible web server and if I use curl to download the URL it works fine. But the test still fails and I can't figure out why. Does the TXT file need to contain some specific text? If so the test doesn't say so.
The URL is https://artooro.com/dvdaz3ruo.txt
This doesn't make sense to me, the error the test gives is "Could not grab the file via IPv6 HTTP".
Needs to be available on HTTP, not HTTPS. Your HTTP redirects to HTTPS, thus the fail.
OK I'll try temporarily turning off the redirect to HTTPS, but I did check the TLS box which I would have expected to make it use HTTPS as it even adds that to the URL that it says it's going to try to test.
Oh, I didn't know there was a TLS option. I passed the cert when it was initially created ;)
It worked over HTTP. My theory is that the test does not support SNI which I'm using.
Yes, the test seems to dislike SNI at this time. I'll make a note of it, and see if that can be improved.
broquea: I've made a few changes from when you last took it. ;-)
Should be happier with SNI now.
