Hi, I’m having a problem with dotnet sonarscanner. Every time it tries to reach /api/settings/values, the scanner fails with Http status code is NotFound. error.
Environment:
- SonarQube version: Community Build / v25.7.0.110598 / MQR Mode
- SonarQube deployed in AWS EKS using Helm Chart
- Dotnet version: 6.0
The endpoint is reachable using my local browser and curl. Below are the log files when I tried to run dotnet sonarscanner using docker image (mcr.microsoft.com/dotnet/sdk:6.0).
