[Kibana 7.2] Kibana Server Not Ready Yet, but no Errors in yml of elasticsearch or Kibana

Hello,

why is my Kibana refusing to start up? These are my YML file of Elasticsearch and Kibana. And further below is my log of ES. There is no [ERROR] in the log, however only [info] and [debug] and [warning]

# ======================== Elasticsearch Configuration =========================


# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch

# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 172.16.3.10
#
# Set a custom port for HTTP:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#dicovery.seed_hosts: ["172.16.3.10"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["172.16.3.10"]

Kibana YML

# Kibana is served by a back end server. This setting specifies the port to use.
#server.port: 5601

# Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
# The default is 'localhost', which usually means remote machines will not be able to connect.
# To allow connections from remote users, set this parameter to a non-loopback address.
server.host: "172.16.3.10"

# The maximum payload size in bytes for incoming server requests.
#server.maxPayloadBytes: 1048576

# The URLs of the Elasticsearch instances to use for all your queries.
elasticsearch.hosts: ["http://172.16.3.10:9200"]

There is something wrong with the elasticsearch server. It seems to be unable to open a previously created .kibana index.
