When I try to clone a repository, authentication fails.

[Daniel Mathers]

When I attempt

       git clone https://<our repository>.git --progress

I get the error

      fatal: Authentication failed for 'https://<our repository>.git'.

My first attempts were in a Docker container running Linux on a windows machine.

• First, I tried authenticating by putting my credentials into the url, like so:

       git clone https://<username - the email I use for Bitbucket>:<my personal access token>@<url of our repository>.git

I have two PATs. One is read-only and one has read and write privileges. Neither worked.

• Then (still in the Linux Docker container) I ran the command 

                git config --global credential.helper store

hoping that it would find the credentials (username: email i use with Bitbucket/ password: read-write PAT) that I have stored locally on Windows. Then I ran

           git clone https://<our repository>.git --progress

after nearly 20 minutes it returned 

          fatal: Authentication failed for 'https://<our repo>.git

• Next I created a file called .git-credentials in the directory I was trying to clone into. The file contained just the line:

          'https://<email>:<PAT>@<repo url>.git'

          (I tried it with an '@' in the email and also with '%40' in place of the '@'. ) I then ran    the commands   

        git config --global credential.helper "store --file .git-credentials" --add

        git clone https://<our repository>.git --progress

         This failed with the same error.

• I then decided to see whether I'd have better luck outside the Docker container. I installed Git for Windows and in the MINGW64 terminal I typed                                  $ git config --global credential.helper manager-core 

         then

          git clone https://<our repository>.git --progress

          A form entitled The Windows Security Git Credential Manager appeared and asked for a username and password. Again I entered my email and PAT. Failure. Then I repeated these steps and entered the password I use to log into Bitbucket. That didn't work either.

If anyone here could suggest something else I might try, I would be deeply grateful.

Another update:

I can also clone from Gitlab into the Docker container.

Update:

I tried cloning one of our repos hosted on Gitlab into the Windows environment. That worked with no issue. My authentication problem seems to be with Bitbucket.

Update:

We've resolved this issue at our end.

Dear moderator: I think you should delete this question, as the problem was actually specific to the way our corporate network works. If someone happens across this post, and has the same problem I was having, their resolution will probably be different.
