Not able to use latest version of Kibana (7.4.0)

I am currently using ELK stack version 7.3.0. I want to use the 7.4.0 due to some upgrade in the TSVB section.I downloaded ELK-stack from their website. Elasticsearch seems to run fine.But Kibana does not open and I get the following error in the command prompt.

Kindly help! Thank you!

It looks like there are issues with the response from Elasticsearch. Can you provide the kibana.yml file?

I got it right. There was a problem with elasticsearch and downloaded the elasticsearch zip again.. and it ran well this time. Kibana also worked.
