Network error black popup with red X appears when there is no error

I have no doubt the intent of the popup "network error" is to inform the user of a problem. However, the popup timing/delay is such that it appears when there is in fact no connection problem, there is simply a delay in loading the page.

Often a page may take a few seconds to load, or when opening a page in a tab, or opening a view/edit a popup - I will see the error without any interference from myself.

I fear that this produces a suboptimal user experience to display an error message when there is in fact no connection problem.

If the trigger for the error is valid and must remain, there a way to increase the delay of the error message popup? Eileen McNaughton
