Hi David,

Then it was a DNS issue.

Hi again,

Apparently the problem is solved. I added the external WMS url to the hosts file where tilecache is located and it worked, at least the tests I've done show that the error mentioned before won't appear anymore. I'll make more test just to be sure.

But, I've noticed that sometimes I get the following error:

An error occurred: Current y value 4793912.353516 is too far from tile corner y 4793894.042969 

Any ideas?

Hi David,

Try to access the URL from the same machine on which you have TileCache installed, and if possible using the same user.

This is not really related to TileCache or urllib2. It is about network access. Are you using a proxy?

Hi Manel,

Thanks for your response. The thing is that the url seems to be not valid, but if I try to access that url via a webrowser after hitting more than five times it creates the image.

You can see what happens :

http://geotiles.ikt.es/cgi-bin/tilecache-2.11/tilecache.py?LAYERS=orto2011etrs89&FORMAT=image%2Fgif&STYLES=&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A25830&BBOX=470986.328125,4785288.0859375,471059.5703125,4785361.328125&WIDTH=256&HEIGHT=256

Another point to take into consideration could be that the layer I'm requesting it's from an external WMS... could that be problem? I mean, could that be the url that it's not finding? Perhaps I should include that URL into my hosts file?

Thanks again.

Hi David,

Your url is not valid or Tilecache cannot contact the server. Check your url is valid. If you are using a proxy think about defining http_proxy and no_proxy variables.

Hi list,

I've noticed that I'm getting the following tilecache error while navigating through the map and creating the tiles on the fly:

An error occurred: <urlopen error (11001, 'getaddrinfo failed')>
  File "c:\python25\lib\site-packages\TileCache-2.11-py2.5.egg\TileCache\Service.py", line 256, in modPythonHandler
    host )

    return self.renderTile(tile, params.has_key('FORCE'))
  File "c:\python25\lib\site-packages\TileCache-2.11-py2.5.egg\TileCache\Service.py", line 138, in renderTile
    data = layer.render(tile, force=force)

    response = self.client.open(urlrequest)
  File "C:\Python25\lib\urllib2.py", line 374, in open
    response = self._open(req, data)
  File "C:\Python25\lib\urllib2.py", line 392, in _open
    '_open', req)
  File "C:\Python25\lib\urllib2.py", line 353, in _call_chain
    result = func(*args)
  File "C:\Python25\lib\urllib2.py", line 1101, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "C:\Python25\lib\urllib2.py", line 1076, in do_open
    raise URLError(err)

Any idea what could be happening?

Thanks in advance.
