To give some more context, I am behind a corporate proxy and I can connect normally to the server instance through Mozilla and also tried with curl:

curl --verbose --proxy 'http://company-proxy:port' 'https//*****/sonarqube/api/system/status'

resulting in JSON:
{“id”:**********, “version”:9.9.1, “status”: “UP”}user

Hello, welcome to the community! And thank you for reporting this.

We identified a regression in the way proxy-related properties are used for connected mode and we published a fix today with version 4.4.2.

Please do feel free to report back here if this new version does not fix the connectivity issue and we’ll do our best to troubleshoot it :slight_smile:

It worked like a charm! Thank you very much :blush:.

Pd: Just for the record, I still had to add some extra JVM arguments in Sonarlint VS Code settings to make it work (like discussed in this other thread):

-Dhttps.proxyHost=company-proxy -Dhttps.proxyPort=port
