Difficulty connecting to Bitbucket Server with Sourcetree

[RS]

Bitbucket v5.1.1

SourceTree 2.7.6

When I try to add my Bitbucket project to SourceTree (or push to the project) I get this error:

git -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree push -v --tags --set-upstream ESL_PPF_Bitbucket refs/heads/master:refs/heads/master
Pushing to https://bitbucket.mydomain.com/projects/ESL/repos/esl-ppf/
fatal: unable to update url base from redirection:
  asked for: https://bitbucket.rccl.com/projects/ESL/repos/esl-ppf/info/refs?service=git-receive-pack
   redirect: https://bitbucket.mydomain.com/plugins/servlet/samlsso?redirectTo=%2Fprojects%2FESL%2Frepos%2Fesl-ppf%2Finfo%2Frefs%3Fservice%3Dgit-receive-pack
Completed with errors, see above

Any ideas?

Can you also check if push works from the command line?

If not, please check with your Bitbucket server admin if there is any change in the URL.
