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

After login, I am navigated to the custom landing page. I get the following error:

Unable to find application file

Grafana has likely been updated. Please try reloading the page.

and
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.

Also, for my dashboard, I have a variable that runs query to show drop down items on the dashboard, Is there a way to wait for page rendering until query has run successfully?
Thanks,
