Why does adding an account to SourceTree fail with authentication error?

[Katherine Morgan]

I can't add my Atlassian account to SourceTree. When I try to add the account, I keep getting this error message:

▲ Authentication failed
Failed to get user details for user [katherine_morgan]
Unable to connect to the host service
An error occurred while sending the request.
The request was aborted: Could not create SSL/TLS secure channel.

When adding the account, I've tried both the HTTPS and SSH protocols and I'm using basic auth.

I want to use SourceTree as my Git client to access my cloud instance of Bitbucket.

Hi Katherine, welcome to the Community!

I'm assuming that you're credentials are right, and the issue must be referring to this line of the error message:

The request was aborted: Could not create SSL/TLS secure channel.

This might be related to the security protocol TLS. TLSv1 and TLSv1.1 was deprecated already deprecated so if you're using an old Sourcetree version you'll need to upgrade. You can download it from our website, and you can read more about the announcement at Deprecating TLSv1 and TLSv1.1.

If this is not your case, can you let us know which Sourcetree version are you using?

Regards,
