Sonarlint Authentication failure on

Visual Studio 2022, 17.5.5, SonarLint, SonarCloud organization account

I am taking over an existing C# solution in our organization and its comes with a sonarcloud project already setup.
Now, when I try to connect SonarLint to this project, I do get an authentication failure:

Connecting to SonarQube server:
Connecting to SonarQube server: Validating credentials
Connecting to ‘’.
Connected to SonarCloud ‘’.
SonarQube request failed: Invalid credentials
Connecting to SonarQube server: Failed

What I did: setup a PAT on sonarcloud, tried to connect through the extension (SonarLint->Connected Mode->Bind to…), used the prefilled server URL, entered the PAT name and the PAT secret.

The same procedure works usually fine on our self hosted server with dozens of projects. But I cant get it to connect to sonarcloud.

Any ideas appreciated.

This sounds suspcious. The UX for providing a token isn’t great. You should only provide the token in the Username/Token field, no other information.
