Subject: [MapProxy] Any clue - could not retrieve WMS map: No response from
 URL
Message-ID: <8b2ac8d5-123b-5a7a-0e35-a3491ba13d50@gmail.com>

Hi
I can?t have the wms source from 
https://daim.lfv.se/geoserver/mais/wms?SERVICE=WMS&REQUEST=GetCapabilities 
working. My config results in mapproxy.source.wms:get_map - could not 
retrieve WMS map: No response from URL - every time.
I can fetch wms images though curl / web reader without any problems, 
but not with mapproxy.

Anyone with a idea whats wrong?

I did see the header - Transfer-Encoding: chunked
in the response, do mapproxy support that?

layers:
   - name: lfv

Hi Michael,

I have tested your layer configuration within my Mapproxy environment 
and it totally worked. So there is no issue with this this configuration.
Maybe something within the global config of mapproxy? Or within your 
application configuration? I am running the Mapproxy in a docker setup 
with nginx.
"No response from URL" sounds like the Mapproxy itself is not running 
properly. If there is a WMS error, the error message would be more 
specific regarding the service.

Good luck for finding the issue!

Greetings,
Daniel

Thank you for testing!!!
It is a bad DNSSEC on AAAA record on daim.lfv.se that made the lookup failed.

Solved it!
