"SonarQube server https://{myserver} can not be reached" in step 3 of Sonar Scanner manual scan

SonarQube: Version 8.7.1 (build 42226)
Sonar Scanner msbuild:
Trying to run a manual scan.

I have successfully setup the server and a reverse proxy in IIS as per the instructions to enable SSL. The IIS server is hosting an internally signed and trusted certificate. My browser shows this as being a valid certificate. The common name is the server and SANs specified for each of the CNAMES, both FQ and non-FQ.

I have created a project and want to run a manual scan.
The project page says to run these commands in the root folder of the solution:

  • SonarScanner.MSBuild.exe begin /k:"{myproject}" /d:sonar.host.url=“https://{myserver}” /d:sonar.login="{mytoken}"
  • MsBuild.exe /t:Rebuild
  • SonarScanner.MSBuild.exe end /d:sonar.login="{mytoken}"

Commands 1 and 2 run successfully, but no 3 errors as follows:

anner analysis

Any ideas why the scanner may not be able to see the server that a) it can see in step 1; b) is visible from a browser in the same session as the scanner.

Can you run the analysis in debug mode and check the http request not able to reach SonarQube ?
It should be this one,

DEBUG: GET 200 https://{myserver}/api/settings/values.protobuf

Then check in your proxy logs if the request reaches it, and if it does check the status code and let us know.

Hi Alex,

Thanks for your reply. I added the “/d:sonar.verbose=true” to the command line for the “begin” step and re-ran the other commands. Adding it to the “end” step is not valid.

The output is as follows this time, so not much more to go on:

I don’t have access to the proxy server to check logs.
Is there a way to specify a proxy server and a server exclusion list?



For anyone else who finds this post in the future and has the same issue, I resolved this by making sure Java knew about our internal certificates.


  • export your root an intermediate certificates from mmc, certificates snap-in
  • in C:\Program Files\Java\jdk-11.0.10\bin:
    ** keytool -import -trustcacerts -alias root -keystore {somefolder}\cacerts -file {exported root cert}.cer
    ** keytool -import -trustcacerts -alias intermediate -keystore {somefolder}\cacerts -file {exported intermediate cert}.cer
  • set two system level environment variables:
    ** SONAR_SCANNER_OPTS=-Djavax.net.ssl.trustStore={somefolder}\cacerts -Djavax.net.ssl.trustStorePassword={keystore password}
    ** NODE_EXTRA_CA_CERTS={exported root cert}.cer
