Can't connect because of 'unable to get secret' error

[Angelo Nikolaou]

Hello,

I didn't realize that the button 'accept answer' marks the question as Solved here, so here we go again.

I can't use Sourcetree to connect to Bitbucket for a month now, even though I used it for two years without a problem.

When I click 'Refresh OAuth Token' I get a 'Confirm Access' page on my browser, then an 'Authentication successful' page. Then, I get the following error in Sourcetree

I have tried the following:

• Deleting all Sourcetree passwords from Windows Credential Manager
• Revoking OAuth authentication from my BitBucket account
• Reinstall Sourcetree
• Different browser
• Connecting with Basic authentication using a different account I have. Even though the password was correct, I still couldn't connect.
• Closed live protection from my antivirus (Malwarebytes Antimalware)

Any help provided would be greatly appreciated!
