Looks like you have enabled HTTPs for Grafana UI access which is not configured properly.
Please refer to the following article that explains how to properly configure the HTTPs for Grafana:
https://community.hortonworks.com/articles/85365/enable-ssl-for-grafana.html
Basically you are getting the following error : private key does not match public key
Which means you have not imported the certificates properly. May be recreating the ssl certificates will be easier and quick approach to fix this issue.
