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

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?
