Hi there! You would need to share a lot more information than that for anyone to be able to help you in a meaningful way. What did you change recently ? Did you upgrade an existing cluster or installed one anew ? What does "unable to open" mean exactly ? What is the error you are getting ? Is there anything in the logs? ---

we have installed latest Elasticsearch and made it as windows service, after that when we try to open in browser [http://localhost:32570](http://localhost:32570) (we modified default port) unable to open the web page in older versions we were able to open this. ---
