Kibana - Port 5601 is already in use. Another instance of Kibana may be running!

Elastic Stack Kibana
1

Im trying to setup ELK stack version 7.5.1 in my 64 bit windows machine. But, im always keep on getting the following error whenever i tried to start Kibana. Also, I checked using netstat -ano | findstr 5601. It returned no results. I just followed the steps given in the official website. Also, i have configured the elastic search hosts in the kibana yml config file.

C:\Softwares\ELK\kibana-7.5.1-windows-x86_64\bin>netstat -ano | findstr :5601

C:\Softwares\ELK\kibana-7.5.1-windows-x86_64\bin>netstat -ano | findstr 5601

FATAL Error: Port 5601 is already in use. Another instance of Kibana may be running!

Its throwing the same error though no other process is using this 5601. Same happens when i give different port number.

Please help me to resolve this. Any help is much appreciated!! Thanks in advance.

Something seems wrong, because if the server couldn't start, I don't think you would see

log [13:46:29.378] [info][listening] Server running at http://localhost:5601

What command are you using to start Kibana, or is this installed as a service?

Based on some tests I did, it looks like your log file is a merge of multiple instances of Kibana.

Can you share more information about what setup steps you followed?

Thanks for your response. I downloaded the kibana set up for Windows and unzipped it. Then, I modified the kibana.yml for elastic Search host. Finally, initiated the kibana.bat from the command prompt.

One more thing I noted is that, same steps working fine in Windows 10 and I can launch the Kibana successfully. But, it's not working in Windows 8.1. not sure that could be a reason but just want to highlight that.

That is strange. It sounds like it could be a bug with the launching script.

Would you mind filing an issue on this behavior at https://github.com/elastic/kibana/issues/new?template=Bug_report.md?
