Embedded Metabase Sprodically Returning "Not Found" when loading

I am running metabase version 46.7 and using the embedded function to display dashboard within our application. Occasionally, when the application loads and attempts to display the embedded dashboard, I get a "not found" response. I have looked in the log in metabase and it also references a not found error.

GET /api/embed/dashboard/[long variable string] 400 2.0 ms (1 DB calls)
"Not found."

If I hit refresh on my application, one or two times the embedded dashboard displays correctly. I have reviewed the size of the instance at EC2 and it is considered over provisioned. I do not think this is an instance size issue. Any other thoughts about what might be contributing to this not found the error?
