In my Excel VBA I try to fill an input field of a web page form, but get always "Automation Error-Interface not found"

In my Excel vba I try to fill an input field of a web page form, but get always "Automation Error-Interface not found". The input field's id is "network" that I can easily get from the html source. My code is:

Sub OpenWebPage()
    Dim ie As Object
    Dim url As String
    
    ' Create Internet Explorer object
    Set ie = CreateObject("InternetExplorer.Application")
    
    ' Set the URL
    url = "https://rb-ddi.ddi.bosch.com/netsearch.html"
    
    ' Make the browser visible
    ie.Visible = True
    
    ' Navigate to the URL
    ie.Navigate url
    
    ' Wait for the page to load
    
    Application.Wait (Now + TimeValue("00:00:10")) ' Wait 10 seconds to be sure that page is opened

    ' Find the input field by its ID and fill it with a value
    Set networkInput = ie.document.getElementById("network") 'here get the error
    If Not networkInput Is Nothing Then
        networkInput.value = "YourNetworkValue" ' Replace with the network value you want to enter
    End If
    
    ' Cleanup
    Set ie = Nothing
End Sub

I get the error at the line

Set networkInput = ie.document.getElementById("network")

I have tried instead of getElementById also getElementByTagName and getElementByName.

The html part where the input field is:

<div class="form-group">
    <label class="control-label col-md-3 col-sm-3 col-xs-12">Network</label>
    <div class="col-md-9 col-sm-9 col-xs-12">
        <input type="text" class="form-control" placeholder="Network Address" id="network" list="networksearch" autocomplete="off">
        <datalist id="networksearch">
        </datalist>
    </div>
</div>
