[MapProxy] invalid wms request from mapproxy

[Oliver Tonnhofer]

Hi Travis,

can you post the relevant parts of the console output/logs?
You can also check out the min_res options. This prevents MapProxy from making requests in in the first zoom levels.

Regards,
Oliver

It appears some cases MapProxy will generate a WMS request with a width=1 and height=3 px.  I think this is related to the source coverage (bbox) in some way.  The source has a fairly small bbox which could be the problem? If I remove the coverage from the source wms it works
