So I was setting up ELK (Elasticsearch, Logstash and Kibana) all in one EC2 on AWS today for demo purposes. I had everything prepared. Elastic IP, correct security group rules, etc.

I figured I would just do quick test before writing filters and templates if I can access Kibana. So I started service for it and tried to open it with Chrome.

Timeout.

Checked config file. Compared it to documentation. Seemed good but changed some things just for sake of change. Restarted service.

Timeout.

Reverted changes I've made in config. Restarted service. Curl on localhost. It work... OK. 😐

It took me half an hour but finally I figured it out after I took my phone and opened it from there. It was working from the beginning. Stupid company network was for some reason blocking this connection. Fuck! 😡And I was restarting that poor service like crazy trying to fix something that wasn't broken.
