QGIS not able to access WMTS (GeoServer specific?)

[qgib]

Author Name: Jonathan Moules (Jonathan Moules)
Original Redmine Issue: 8401
Affected QGIS version: master

---

QGIS can't seem to access my WMTS (GeoServer 2.3.4). I can see it has made the request in the access logs, and the same URL works fine in the browser (and ArcMap can access it fine too), so I'm concluding it's a QGIS issue.

When I click "connect" it swaps to the "server search" tab. But there's nothing listed. I didn't tick any of the boxes for the connection.

My GeoServer isn't publicly available (security approval required - ongoing). I can't get my QGIS to access the internet either (it doesn't like our proxy) so can't test other WMTS'.

Attached is the GetCapabilities.

Turns out this is different to #17178

Further to that bug report I've expanded the URL but it hasn't fixed the issue.
This URL works fine in the browser and returns the previously attached file.

Found the same problem (QGIS 2.1 on WinXP 64): WMTS provided by default Mapcache 'demo' page works on QGIS 1.8 and 2.0, not on master version.
The map extension is correct, but the WMS log reports 'image is NULL' and:

Download of GetLegendGraphic failed: Error downloading http://192.168.122.128/mapcache/?SERVICE=WMS&VERSION=1.1.1&SLD_VERSION=1.1.0&REQUEST=GetLegendGraphic&LAYER=test&STYLE=default&SCALE=235105735.596957&FORMAT=image/png - server replied: Method Not Implemented

Um, might actually be something different. That fixes the problems after GetLegendGraphic failed. Feel free to reopen.

Would this be in the build weekly QGIS-OSGeo4W-2.1.0-46-Setup-x86_64.exe - 18-Nov-2013 20:22 - number e882e47 from - http://qgis.org/downloads/weekly/?

Because if it is, this bug isn't fixed - I'm still getting the exact same behaviour.

Thanks! I guess that'll be in tonight's weekly build?

Hi Jonathan, looking into the fix of jurgen, it seems there is was a missing default style.

So I thought to check the validity of the capabilities (using xmllint) and as you can see below it is just not valid against it's schema (it is missing a Style element :-) )

So maybe try to create a style for that layer (maybe that helps)? Or otherwise issue a bug against the software (Geowebcache/Geoserver?)?

If I take one of the national dutch wmts services (also running geowebcache I think...), these are validating:
http://geodata.nationaalgeoregister.nl/tiles/service/wmts/aan?VERSION=1.0.0&request=GetCapabilities

Below the command for the validation of your service:

richard@kwik:/tmp$ xmllint --noout --schema http://schemas.opengis.net/wmts/1.0/wmtsGetCapabilities_response.xsd wmts-getcapabilities.xml

That's fixed it.
And wow, this is awesome. Compare it to the ArcGIS WMTS implementation which is utterly awful and totally unusable. Go QGIS! :-)

Oh, and GeoServer ticket opened and acknowledged as a bug - https://jira.codehaus.org/browse/GEOS-6190
