With Wireshark I found out that the GET string ends up like:  
[http://192.168.13.50:8080/xml/json.php%3Fmode=infomin](http://192.168.13.50:8080/xml/json.php%3Fmode=infomin)

So the reply of the SmartMeter is 404 page not found because of the %3F in the URL.  
The big question is also how to get the ? in the URL instead of %3F replacement...
