Dashboard Request Data error - ! Exclamation point - Stackdriver plugin


I have connected my grafana using the Stackdriver plugin to my GCP project.
After 2 hours all the panels in the dashboard stop working and show a red ! Exclamation point.
By using the Chrome development tool for troubleshooting the issue I see in the console tab:

“Failed to load resource” related with google oauth2.
After 15 mins it resolved by himself without do a refresh of the page.
This is happening almost every 2hours.
Any suggestions how I can fix that? Where and What I need to configure?
I dont think that its something that I can add to grafanas config file but maybe someone of you have faced similar issue and know the answer.


Many thanks,
