Yep I have also the same error:The following error was encountered while trying to retrieve the URL: http://jenkins.trisquel.info/makeiso/iso/
Connection to 188.165.228.124 failed. The system returned: (111) Connection refused The remote host or network may be down. Please try the request again. It seems the server with the jenkins is down. Last week was working and I downloaded a trisquel 8 iso and tried.
