SourceTree push not working in Bitbucket tutorials

Question

I'm hoping this is something simple, but I am having difficulty getting a simple "push" to work with these two SourceTree Bitbucket tutorials:
https://bitbucket.org/tutorials/sourcetree-starter-b/src
and
https://bitbucket.org/tutorials/bucket-o-sand

I get the message: "fatal: Authentication failed for 'https://ahm126@bitbucket.org/tutorials/bucket-o-sand.git/'

I am able to push to private repositories I have set up, just not to the tutorial ones.  I'd like to get this working for a class I am teaching...

Thanks,

Andrew

I did just now attempt to fork the bucket-o-sand repository (URL referenced above) and then cloned using SourceTree.  I made a change, commit and push, but get the same error message (see attached image).

Thanks for your assistance in attempting to figure this out!

I'll check with the author and find out what the scoop is. Thanks for bringing it to our attention!

John,
Can you elaborate, please?

The tutorial says nothing about creating a fork of the repository prior to pushing to the tutorial repository.  This would be in the bucket-o-sand repository (https://bitbucket.org/tutorials/bucket-o-sand) at this location in the tutorial ("Make a commit and push a change").

If it is required to fork the repo, the tutorial text needs to be updated, I think.
Thanks
