VB script has error "Security certificate required to access this resource is invalid" from msxml3.dll, and option 13056 not working

I am having this issue now, with code:

set xmlhttp=CreateObject("Microsoft.XMLHTTP")
xmlhttp.Open "Get" url, false, proxyUser, proxyPass
xmlhttp.send

Then I am having this error: "Security certificate required to access this resource is invalid" from msxml3.dll

I searched a bit and found that using option 13056 might help, so I added this:

xmlhttp.setOption(2)=13056

But was reminded that "Object doesn't support this property or method: 'xmlhttp.SetOption'". I also tried:

xmlhttp.setOption 2, 13056

The outcome is the same. I also checked the object xmlhttp, which is not empty/NULL.

So what should be the fix?
