Hi,

Yes, it seems to be OpenLayers question then. However, do still capture the requests because without them you cannot understand what happens really.  My guess is that something in wrong in how EPSG:31467 and EPSG:32740 are used and OpenLayers is requesting data from a place where there are no data.

and they are working. Also I checked it in QGIS and there I can load it
too.

I am using myself Fiddler2 proxy but I suppose that Firebug can show you what OpenLayers is sending and high enough TinyOWS logging level will also gather requests into tinyows log. The software is not important but you just have to get the requests so you can resend them with a browser or some other tool that yuo can control and see what happens. You can also include the requests in your further mails. Then the question will be "OpenLayers is sending this and TinyOWS is sending back that, what's wrong?" and it will be much easier to answer.
