Authentication bitbucket issue

[Michalina Tylska]

Hi,

I'm authenticated on SourceTree (via API Token) yet I can't fetch, push to remote repository:

Hi @Michalina Tylska ,

Any chance you can try using OAuth instead of API tokens? I've seen a couple of discussions around this and it would seem that OAuth works much better than this method. 👀

Also, if we're talking about API tokens, can you maybe try clearing out all auth credentials from credential manager and then re-adding the token to see if that will help?

There are a couple of discussions/questions and answers around this area, so I'd recommend checking them out:

Hi @Tomislav Tobijas ,

Thank you for this.

I have tried clearing Credentials and reinserting API token and that didn't change anything.

For the OAuth seems like that didn't change anything as well and error still occuring.

Hi @Michalina Tylska ,

Just to confirm - you're on Mac or Windows? Also, which version of Sourcetree are you currently running?

There's also this suggestion by another user on the existing bug report:

...After upgrading the embedded Git in SourceTree then it started to work...

Potentially this could work 🤔

Cheers,
Tobi

Thanks! I'm on Windows 11 and I got the latest version of SourceTree: 3.4.31. I tried adding API token to URL and still get the error. I had run through this forum for few days now and tried few (if not all) suggested fixes but still no luck so I decided to post myself to see if that would get me anywhere.

Ah, that’s unfortunate... 😕

Any chance you could try authenticating with the same API token on another device? That might help determine whether the issue is related to your Bitbucket account/token or something specific to the current Windows/Sourcetree environment (most likely, we're talking about this).

[Michalina Tylska]

Hi, I don't have access to any other device unfortunately.

I have run a command:

curl -I -H "Authorization: Bearer <my token>" https://api.bitbucket.org/2.0/repositories

and got the message :

'' HTTP/1.1 401 Unauthorized
Content-Type: application/json

...''

I have ticked all the scopes when I created my token.

I know this one is little bit old but you never know:
