[MapProxy] OSM Tileserver Tileorder Problem

[Frederick Löbig]

Hi List,
Glad I found this mailing list because I'm pretty new to Mapproxy. What I've seen so far is very impressive!!
So, I got almost everything running fine. The core idea is, to use mapproxy as a proxy to provide OSM Tileserver tiles via a WMS, because the software I am using can't handle direct Tileserver requests and therefore has to use WMS. I've been playing around with rendering OSM tiles by myself with PostGIS and GeoServer, but either seeding the tiles with GWC or directly rendering the maps needs a lot of server power as all of you might know. So I thought, Mapproxy is the way to go!
The problem I have now is: I have the mapproxy up and running and when I add a WMS layer, the tiles appear, so no problem with the data connection there. Unfortunately, the tiles are in the wrong order, even with the recommended "origin" setting. You can find a screenshot of the resulting map here:

The configuration file I am using is the following (I have tried to have it very compact, so that it's not confusing):

I can imagine, that it only is a very small thing I forgot or misconigured. Hopefully, some of you can help me with this :)
Thanks in advance,Freddy
