I get HTTP error 404 when I try to clone the tutorial repository to my local drive with SourceTree/Mercurial/Bitbucket. The source address is https://phell@bitbucket.org/phell/tutorial.gitand Mercurial support looks enabled in SourceTree under Options.
Earlier I removed an error by adding
[hostfingerprints]
bitbucket.org = 67:b3:bf:9f:c5:38:0e:4c:dd:4e:8a:da:3d:11:1b:c2:a5:d1:6c:6b
in the mercurial.ini file so I guess SourceTree at least is trying to communicate with Bitbucket.
