I agree, the error indicates a problem with the proxy, but don’t know where to look for cause.
When run curl command with proxy to sonarcloud.io/batch/index it is working correctly. I’ve seen in this topic: Sonar-scanner-maven does not work with HTTP (not HTTPS) PROXY authentication that sonar-maven plugin does not work with proxy settings, isn’t that right?
Regarding the sonar-scanner I got reply from network team that sonarcloud.io is allready whitelisted. Is there other option I can set/provide to sonar to enable connection or am I missing something?
Thanks for quick reply,
Oskar
