Hello, I have installed Elastic, but after 2-3 days stops working with the following error. {"statusCode":503,"error":"Service Unavailable","message":"License is not available."} Could you help me with investigation why its happaning ? cat /etc/redhat-release CentOS Linux release 7.9.2009 (Core) bin/kibana --version 8.6.2 bin/elasticsearch --version Version: 8.6.2, Build: rpm/2d58d0f136141f03239816a4e360a8d17b6d8f29/2023-02-13T09:35:20.314882762Z, JVM: 19.0.2 ---

> [@R1d3rBG](#): > > {"statusCode":503,"error":"Service Unavailable","message":"License is not available."} I also got this error when my actual elastic url was `https://localhost:9200` and I set `http://localhost:9200` in kibana.yml. If you have SSH enabled in elasticsearch, check the url in `kibana.yml` and it should be https and `https`. On the other side there can be other reasons to this. I have mentioned my case in which i got this error. ---

Thanks for your reply. No, I didnt change it to https, I'm using http. After rebooting of the machine works fine for several hours, but it fails in the end. I'm able to see this error in kibana logs: "License is not available, authentication is not possible.","log":{"level":"ERROR","logger":"plugins.security.authentication"},"process":{"pid":2414},"trace":{"id":"f447e50c1e57107daa15e35cd6939541"},"transaction":{"id":"8468a3a52ea55e95"}} ---

What is the result of a curl to your elasticsearch server from the kibana machine? `curl http://your-elastic-ip:9200` ---

Are Kibana and Elastic running on the same server? If this request was from the Kibana server then it can talk to Elastic without any issues. Did you change the default configuration? Per default version 8 will enable security and https, since you have http something was changed. Can you share both your `elasticsearch.yml` and `kibana.yml`. Also, share the logs of your Elasticsearch for the same time frame when you have the error in Kibana. ---

Yes, both are running and it works fine for a few hours after rebooting the machine. Here is kibana.yml. I removed all unnecessary comments# ```auto server.port: 5601 server.host: "myipishere" server.name: "еlk01" elasticsearch.hosts: ["http://myipishere:9200"] elasticsearch.username: "kibana_system" elasticsearch.password: "mypasswordhere" logging: appenders: file: type: file fileName: /var/log/kibana/kibana.log layout: type: json root: appenders: - default - file pid.file: /run/kibana/kibana.pid ``` here is the elastic.yml ```auto cluster.name: bgelk node.name: elk01 path.logs: /var/log/elasticsearch network.host: ["localhost", "myipishere"] http.port: 9200 discovery.type: single-node xpack.security.enabled: true xpack.security.enrollment.enabled: true xpack.security.http.ssl: enabled: false keystore.path: certs/http.p12 xpack.security.transport.ssl: enabled: false verification_mode: certificate keystore.path: certs/transport.p12 truststore.path: certs/transport.p12 http.host: 0.0.0.0 ``` I have cleared the log because it was huge and hard to read. I will paste it once the issue is reproduced again. ---
