I am trying to connect to http://challenge01.root-me.org/web-serveur/ch10/ in Firefox with FoxyProxy and OWASP ZAP and I got this error message
ZAP Error [java.net.ConnectException]: Connection refused (Connection refused)

Then I tried to find out where the problem lies. I tried to do the same on the command line: When I call curl http://challenge01.root-me.org/web-serveur/ch10/, I get the correct result. But when I start OWASP ZAP and call the command curl --proxy 127.0.0.1:8080 http://challenge01.root-me.org/web-serveur/ch10/, I get the same error message.
Then I tried the same with another site from me https://www.mysite.com. I tried all the same things and I could connect to my site using OWASP ZAP.
So, what can I do to find out why it does not work with http://challenge01.root-me.org/web-serveur/ch10/ but with https://www.mysite.com?
Edit
My proxy settings for OWASP ZAP are these
