[MapProxy] WMTS-Source: could not retrieve tile

[Siegel Andreas]

Hi!

This is my first post and i am a newbie in mapproxy.

So.
My goal ist o create a local tile cache in our native srs (31254) from an external WMTS (http://maps.wien.gv.at/basemap) which is only provided in 3857.
As a first step i just want to see the external WMTS in my MapProxy-Demo.

But this fails.
In mapproxy.log i find:
...
WARNING - mapproxy.source.tile - could not retrieve tile: No response from URL "http://maps.wien.gv.at/basemap/bmapgrau/normal/google3857/7/45/67.png": timed out
...

The URL ist perfectly fine.
wget "http://maps.wien.gv.at/basemap/bmapgrau/normal/google3857/7/45/67.png" -o 67.png 
delivers a nice little PNG-image.
This at least suggests the configuration not being to much off the mark.

Now comes the strange part.
I cannot find any network-requests for http://maps.wien.gv.at/basemap... using a packet analyzer (wireshark)
How is this possible? Or better. Does mapproxy not query the internet but rather some local storage resp. cache?



Relevant snippets from my mapproxy.yaml:
.
  - name: basemap_layer
    title: Basemap
    sources: [basemap_cache]
.
  basemap_cache:
    format: image/png
    request_format: image/png
    grids: [webmercator]
    sources: [basemap_wmts]
.
  basemap_wmts:
    type: tile
    url: http://maps.wien.gv.at/basemap/bmapgrau/normal/google3857/%(z)s/%(y)s/%(x)s.png
    transparent: false
    grid: webmercator
    coverage:
      bbox: [977650, 5838030, 1913530, 6281290]
      srs: 'EPSG:3857'
