I'm trying to start Elasticsearch from the command line when I get the error mentioned above. Thank you in advance for all your help. Regards, Peter ---

Something (probably elasticsearch) is already running on that port. That's why you can not launch it again. ---

Indeed that seem to have been the problem. Don't know why or how elasticsearch started twice, I could not see it in Task Manager, but after a restart of windows I was able to start elasticsearch manually from the command line. Thank you for your help 🙂 ---
