Cannot restart service grafana-server restart

I install Grafana cloud in my Ubuntu 18.04 64.
I update plug by “grafana-cli plugins update-all” in my Ubunt. However, when I “service grafana-server restart”, nothing changed.
When I “service grafana-server stop”, my Grafana.net keep working. It seesm my Grafana.net is not conneted to my linux.
How to restart my grafana service?

I do not understand what you mean by “installing Grafana cloud”.

Grafana cloud is an online service which you use without having to install
anything on your own machine.

I saw there is local Grafana. Therefore, I cannot figure it runs on local or cloud.
I use Multistat v1.7.1, Pie Chart v1.6.1,Treemap V0.8.0 and want to update.

I run these commands:
grafana-cli plugins update-all
service grafana-server restart
But the plugins keep the original versions.
Thanks for your help
