QuerySelectorAll - returns null - html

Question

I'm having a weird problem with Excel build version and a macro.
Basically, the macro reads a html page and does a queryselectorAll for a specific table ID and tag.
The code runs smooth as butter on my machine and for other users.
We all have version 16.0 (Office 365) and build 13801 (from application.version and application.build).
The user for which the macro doesn't work has the build 14326.
Does anything change between the 2 different build version ? I'm confused ...
The error is generated by the object inputBoxes that remains Null.
All the users are printing the line Debug.Print html.body.innerHTML just fine.
I've tried with a different selector html.querySelectorAll("td") but the error remains the same.
The macro goes :
Public Sub getGDIN(cp12 As String, adl As Integer, frm As UserForm)
Dim http As New XMLHTTP60
Dim html As New HTMLDocument
Dim response As String
With http
.Open "GET", "http://me.intra-dmu-13/gdi.asp?Type=P&cp12=" & cp12, False
.send
If .Status <> 200 Then
MsgBox "Unable to load the requested page (GDI)", vbCritical
Exit Sub
End If
response = StrConv(.responseBody, vbUnicode)
End With
html.body.innerHTML = response
Dim inputBoxes As Object
Dim i As Long
Dim ctrl As Control
Set inputBoxes = html.querySelectorAll("#Table3 td")
'Set inputBoxes2 = html.querySelectorAll("td") <--- same error
Debug.Print html.body.innerHTML ' <--- print the whole html (both build version)
If inputBoxes.Length < 32 Then ' <--- ERROR NULL
MsgBox "Nothing has been found with this file number.", vbInformation
frm.btnGenerer.Enabled = False
For Each ctrl In frm.Controls
If ctrl.Name Like "tb*adl" & adl And Not ctrl.Name = "tbCp12_adl" & adl Then
ctrl = vbNullString
End If
Next ctrl
Exit Sub
End If
' ...
End Sub
In addition, here is the generated html (since it's from an Intranet) :
<TABLE id=Table3 cellSpacing=0 cellPadding=0 width="100%" border=0>

The variable cp12 passed into the sub in simply a string that contains a file number to query our ministry database.
If anyone can shed some light ... or maybe suggest a different approach.
Thank you.
