I can't clone a repository from Bitbucket

[Diego Mendes Garcia]

I have the repository access in Bitbucket and when I try to clone it with Sourcetree, this message shows up:

Command: git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote https://diegogarcia16@bitbucket.org/Lynx_Process/lynx-rtp-projeto.git
Output:
Erro: remote: You may not have access to this repository or it no longer exists in this workspace. If you think this repository exists and you have access, make sure you are authenticated.
fatal: Authentication failed for 'https://bitbucket.org/Lynx_Process/lynx-rtp-projeto.git/'

I allready tried to reinstall Sourcetree, call support, but nothing works
