We did try to see if there is any difference in behavior in case parameters are swapped, but seems like there is no issue on our side. In this case, we need to know more about your setup, do you have any proxy or anything in between your SonarQube and your browser?
I identified the problem. The URL suggested in the action is using HTTP, but via the browser we have an certificate for all URLs using HTTPS like SonarQube. Changing the action URL to HTTPS works for me.
