Invalid Azure URL or Personal Access Token

I am using SonarQube 9.9 Developer Edition, deployed on Docker. The SonarQube server runs over HTTP.
I’m in process of connecting to Azure DevOps Server (on-premise, self managed). The Azure DevOps Sever runs over HTTPS .

I followed the instructions an receive “Invalid Azure URL or Personal Access Token”
The logs files show:

ERROR web[AZRGgOyJpysbh1yOAD0m][o.s.a.c.a.AzureDevOpsHttpClient] Unable to contact Azure DevOps server for request [https://[AzureDevOpServer_URL]/tfs/DefaultCollection/[My_Project]/_apis/projects?api-version=3.0]: [PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target]

What steps should I take to make it work ?

Hey there.

Look at the docs here.
