Kibana UI is not up but the container is up and running

I am upgrading Elasticsearch as well as Kibana from 5.6.14 to 7.4.2

My ES is up and running

Hitting http://10.236.220.130:9200/_cat/indices?v in browser
gave me below output

Contents of elasticsearch.yml

http.host: 0.0.0.0

Tried to start the kibana container, Container is up but in UI I am getting {“statusCode”:404,”error”:”Not Found”,”message”:”Not Found”} or sometimes kibana is not ready to start message
this is my kibana.yml

server.host: "0.0.0.0"
server.basePath: "/clog"
server.rewriteBasePath: false
elasticsearch.hosts: [ "http://localhost:9200" ]
xpack.security.enabled: false
kibana.index: ".kibana"

I get following in logs

I used node:10.15.2-alpine image on top of it adding kibana7.4.2 using kibana-7.4.2-linux-x86_64
Also I tried using docker.elastic.co/kibana/kibana:7.4.2 still getting same error log

Note we dont have licence to use x-pack So we need to disable it whereever it is used. I donot know what is missed out. Any help will be highly appreciated
