Visual Studio 2022 SonarLint Connection Mode to SonarQube reconnection issues

Please provide

  • Operating system: Windows 10 Enterprise
  • SonarLint plugin version:
  • Programming language you’re coding in: C#
  • Is connected mode used: Yes
    • Connected to SonarCloud or SonarQube (and which version): SonarQube Enterprise Edition - Version 8.9.8 (build 54436)

In visual studio 2022 enterprise addition I’ve set up the Connection Mode to SonarQube. I created a token and I’ve used it to connect successfully. I then close Visual Studio 2022 then reopen Visual Studio 2022 the Connection Mode is giving an error “Cannot connect to the SonarQube server. Make sure you provided the correct connection information, including your sign-in credentials, and try again.
See more information in the output window (SonarLint).”

I can then reenter the the token re-establish connection. I would expect that this should just reconnect without issue.

I also updated the settings.json file to be without avail.

  "sonarlint.rules": {},
  "sonarlint.connectedMode.connections.sonarqube": [
      "connectionId": "XXXXXX", // id of your sonarqube server
      "serverUrl": "", // url of your sonarqube server
      "token": "XXXXXXXX" // token to authenticate with sonarqube}],

Any thoughts on a way to fix this?

Welcome to the community!

You’re connecting the very latest version of SonarLint for Visual Studio to an outdated, EOL version of SonarQube. I know we did a lot of work in the SonarQube 9-series to improve support for connected mode (among other things), so I’m not surprised you’re experiencing flakiness. I wouldn’t be surprised if some of the APIs have changed.

Can you get your SonarQube admins to upgrade your instance and try again?
