Grafana quick link UI is giving ERR_SSL_PROTOCOL_ERROR error.

[#1]

when i click on grafana UI then it will take me to the a different page and there its giving

This site can’t provide a secure connection

<hostname> sent an invalid response.

ERR_SSL_PROTOCOL_ERROR

[#2]

I have one more cluster and there grafana is working fine.

I thing i observe there is:

https://<hostname>:8443 --- my ambari address

And when i click on Grafana UI link its:

http://<hostname>:3000

so the difference here is grafana is going to http here not on https.

can you tell me how can we resolve this?

Can you please try the following to see if it fixes your issue?

1. Edit /etc/ambari-server/conf/ambari.properties to set the empty values:

http.strict-transport-security=
views.http.strict-transport-security=

2. Restart ambari server

ambari-server restart

3. Clear the browsers cache (or for testing open the browser in "Incognito mode") then access the grafana UI. Please have a look at the HSTS setting of browsers : http://classically.me/blogs/how-clear-hsts-settings-major-browsers

.
