Can't login to kibana, login screen keep reappearing

[elasticforme (Sachin)]

I had everything working.
then started testing https

now I want to go back to http:// connection.

I reverted all the changes.
I can start elasticsearch and can connect to cluster using username elastic

[root@elktst01 kibana]# curl -u elastic 'http://elktst01:9200/_xpack/security/_authenticate?pretty'
Enter host password for user 'elastic':
{
  "username" : "elastic",
  "roles" : [
    "superuser"
  ],
  "full_name" : null,
  "email" : null,
  "metadata" : {
    "_reserved" : true
  },
  "enabled" : true,
  "authentication_realm" : {
    "name" : "reserved",
    "type" : "reserved"
  },
  "lookup_realm" : {
    "name" : "reserved",
    "type" : "reserved"
  }
}

but when I try username elastic/password on kibana same page is keep refresing.
I can't login to kibana with any other username that I had created

what happen here?
I got the kibana logo.
