I too am encountering this error. A user on mrexcel fourm (jonathanwang003) explains that the new URL uses Unix Timecoding for dates. The updated VBA code would look something like this:

qurl = "https://query1.finance.yahoo.com/v7/finance/download/" & Symbol
qurl = qurl & "?period1=" & (StartDate - DateSerial(1970, 1, 1)) * 86400 & _
       "&period2=" & (EndDate - DateSerial(1970, 1, 1)) * 86400 & _
       "&interval=1d&events=history&crumb=" & **Crumb**

QueryQuote:
With Sheets(Symbol).QueryTables.Add(Connection:="URL;" & qurl, Destination:=Sheets(Symbol).Range("a1"))
    .BackgroundQuery = True
    .TablesOnlyFromHTML = False
    .Refresh BackgroundQuery:=False
    .SaveData = True
End With

The missing piece here is how to retrieve the "Crumb" field that contains cookie information from the browser. Anyone have any ideas. I found this post, which may help: https://www.mrexcel.com/forum/excel-questions/1001259-when-using-querytables-what-posttext-syntax-click-button-webpage.html (look at last post by john_w).
