Every once in a while, valid login information is rejected. Closing/reopening SourceTree solves this.

I've seen this only happen at BitBucket, but that might be because I use that the most.

Steps that happen:
1- push a commit to BitBucket
2- provide valid user/password credentials
3- you get an "abort: authorization failed"
4- retry: same "abort: authorization failed"
5- restart SourceTree: success.

This is the log:
