The WebDAV-Server behind box.com dont starts at the ROOT-Level (starts at /dav/).
I think, the ubuntu backup tool (or the library) test the WebDAV-http method on root level and stop working.
1. CURL -v -X "OPTIONS" http://www.box.com/
< Allow: GET,HEAD,POST,OPTIONS,TRACE
2. CURL -v -X "OPTIONS" -u "boxemail:boxpassword" http://www.box.com/dav/
< Allow: GET, PUT, DELETE, MKCOL, OPTIONS, COPY, MOVE, PROPFIND, PROPPATCH, LOCK, UNLOCK, HEAD
Like other webdav server implementations you should test WebDAV at the given path, not at ROOT!
