I applied OS updates to my Ubuntu box on the weekend and in that process it upgraded Grafana to 2.5 (I think). I now get an error when trying to start Grafana with service grafana-server start The /var/log/grafana/grafana.log reports this:
To get Grafana to load I then changed the port in /etc/grafana/grafana.ini to 8443 and it loads fine and I can view my data etc. Port 443 isn't being used by anything else so I'm not sure where else to look Things all work OK on 8443 however the import of the new dashboards as per your blog post ( http://blog.pkiwi.com/grafana-2-5-support-with-netapp-harvest/ step 3 ) fails as it tries to talk to port 443. I tried putting my server IP in the conf file but that still failed.
Any ideas where I can look to see why I can't load it on port 443.
