Type in https://yourusername.databox.me/ . For me it was https://bshambaugh.databox.me/ .
A certificate authentication should be presented. Make sure you are presented with the client certificate that was created by the method of the previous post (or if everything was done manually, in the same form as the result). Press okay. If you see the certificate again, press okay again.
Enter location of the LDP server. In this case, https://bshambaugh.databox.me/ .
If all goes well, you should see the contents of your "file system" . That is the Linked Data Platform Resources which consist of Linked Data Platform Containers (LDP standardized RDF) and RDF and non-RDF resources (binary or text) .
I see things served from the URL http://linkeddata.github.io/warp/#/list/https/bshambaugh.databox.me/ .
Edit: It is also a useful exercise to start this process with something like https://bshambaugh.databox.me/storage/ in the browser bar with https://bshambaugh.databox.me/storage/ as the location for the LDP server. Occasionally, this can fail with a 304 Not Modified Response or even a CORS failure as it did later when I tried it again. I started out with https://bshambaugh.databox.me/storage/ when I first discovered this process.
