Hello everyone,
It seems that something is blocking ES on my machine

At this point, when I try to do a curl, nothing happens. I tried with both ES 2.3.4 and ES 5.6.2.
I think it is probably due to some previous instance of ES still running somewhere but I could not find any with the ps command.
Thank you for your help!
