Drush error during adding an install profile as platform In Aegir, I add a platform with a buildfile:

core = 7.x
api = 2
projects[] = drupal
projects[profiler_drupal_base][type] = "profile"
projects[profiler_drupal_base][download][type] = "git"
projects[profiler_drupal_base][download][url] = "git@bitbucket.org:joachimroeleveld/profiler_drupal_base.git"
projects[profiler_drupal_base][download][branch] = "master"


I made an install profile which I pushed to the my public repository containing a .info, .make and .profile file (and the .build file so Aegir can read it). 

After a bunch of tasks Aegir succeeded running (including downloading Drupal; the first step of the build file), I get this erors: 

Unable to clone profiler_drupal_base from git@bitbucket.org:joachimroeleveld/profiler_drupal_base.git.
Could not download platform using drush make. No platform present


Is something wrong with the structure of my repo?
The solution for me was to use the HTTPS-link instead of the SSL-link.

projects[drupal_development_base][type] = "profile"
projects[drupal_development_base][download][type] = "git"
projects[drupal_development_base][download][url] = "https://joachimroeleveld@bitbucket.org/joachimroeleveld/drupal_development_base.git"
projects[drupal_development_base][download][branch] = "master"
