Questions about localhost:5601
- What is port 5601?
- The default port of Kibana.
- Why does Kibana say server is not ready?
- It cannot connect to Elasticsearch yet. Check Elasticsearch and its credentials.
- Is localhost:5601 safe?
- Yes while it stays on localhost. Tools like this often show sensitive data, so keep them off the public internet and put a login in front of them if other people can reach the port.
- Can I use a different port instead of 5601?
- Yes. Pick a free port above 1024, set it in the program, and open that number instead. If other programs connect to this port, change it there as well.
- How do I check what is using port 5601?
- Use the port checker on this page. It shows the command for Windows, macOS and Linux and does not send anything to this site.
