[Bug-wget] wget ignores --no-check-certificate if started by Powershell Script

[gooly]

Hi,
I have no idea what can I do. It has been working last Sunday but now it 
fails again - the same script!!

I want to download a https-page every Sunday evening and I want wget to 
ignore the certificate of the https-page!

PS-So my script has:

 $urlDFx  = "https://www.dailyfx.com/calendar/";
 $argList = " $urlDFx -O $rawDFx -o $logDFx --no-check-certificate "
 $wg = Start-Process wget -wait -NoNewWindow -PassThru -ArgumentList 
$argList

The other variables are names of my local files - if you know wget you 
will know.

Last Sunday this worked perfect if I run it in the ps-cmd and in 
Powershell's ISE but it fails regularly if the script was called by the 
task scheduler.

Finally I got the task-scheduler-call to work by adding --verbose:
 $argList = "$urlDFx -O $rawDFx -o $logDFx --no-check-certificate 
--verbose "

But today (Sunday again) the task-scheduler call failed and now even the 
call in the ISE failed???

The error is always the same:

> --2016-02-14 21:23:26--  https://www.dailyfx.com/calendar/
> Resolving www.dailyfx.com... 104.87.22.147
> Connecting to www.dailyfx.com|104.87.22.147|:443... connected.
> WARNING: cannot verify www.dailyfx.com's certificate, issued by 
`/C=US/O=GeoTrust Inc./CN=GeoTrust SSL CA - G3':
>   Unable to locally verify the issuer's authority.
> WARNING: certificate common name `fxcm.com' doesn't match requested 
host name `www.dailyfx.com'.
> HTTP request sent, awaiting response... 403 Forbidden
> 2016-02-14 21:23:26 ERROR 403: Forbidden.

So:
1) wget accesses the url but
2) ignores the option --no-check-certificate
3) stops the dld of the https-page but
4) tries the http-page and fails with a 403-error

What do I have to do that wget called by my Powershell script
=>  _FOR SURE_  (!!)
loads this https _IGNORING_ the certificate!!

Thanks in advance!
