Kibana no longer works (6.4.0)

[Constantine_Abayeu]

Hello,
We have run through incremental upgrade on our test cluster.
Everything seems to be working fine, except Kibana.
I am able to start it. It seems to connect fine and even receive data, according to log.
However I am no longer able to access the web kibana dashboard...
It is set up with TLS in place. and if I put 6.3 with the same config it works just fine.

Also my Monitoring cluster reports that kibana is aliveand kicking.

Below is my kibana config:

server.port: 5601

server.host: 127.0.0.1

elasticsearch.url: "https://servername.company.com:50000"
elasticsearch.username: SECRET_ID
elasticsearch.password: SECRET_PASSWORD

console.enabled: true
xpack.security.enabled: true
server.ssl.enabled: true
server.ssl.certificate: /etc/kibana/certs/servername.company.com.pem
server.ssl.key: /etc/kibana/certs/servername.company.com.pem

elasticsearch.ssl.certificateAuthorities: [ "/etc/kibana/certs/company-root-ca-g3.pem" ]

server.ssl.certificateAuthorities: [ "/etc/kibana/certs/company.root.pem" ]


xpack.security.encryptionKey: RANDOMLY_GENERATED_STRING_THAT_IS_VERY_LONG

my server.host used to be ::0 before and worked just fine, however with 6.4 it would not let kibana start, saying connection was refused. So i changed that to 127.0.0.1

Elasticsearch on its own works as expected still.... all hosts are alive and whatnot.

Please help T_T

Are you trying to access Kibana from localhost? If not, you'll want to set server.host to the machine's public ip.

Thank you! this have worked!

also setting it to 0.0.0.0 also worked - in case anyone else needs to do that
