Grafana Errors on Initial Load: Unable to find application file error

I’m using Grafana v7.3.3 connected to a PostgreSQL. I have it running in a Kubernetes environment using ISTIO. When initially loading the dashboard, I get the following error:

Unable to find application file
Grafana has likely been updated. Please try reloading the page.

Loading chunk 1 failed…

when I reload the page, I get the following errors:

and

“upstream connect error or disconnect/reset before headers. reset reason: connection failure”

After waiting for several minutes and performing multiple refreshes, the dashboard will eventually load. Any recommendations on how to resolve the issue is greatly appreciated.
