[MapProxy] 404 error when attempting to seed from arcgis source

Thanks again for digging into this further!
I have it working now with the http://server.arcgisonline.com/arcgis/rest/services/World_Street_Map/MapServer url !!
The capabilities page for the arcGIS server I am working with does not have the "Tile Info" section. Is this what I am missing? (i.e. this is required by MapProxy to request the tiles to seed? I sent the link to the arcGIS online capabilities page to our arcGIS server provider and questioned whether this information needs to be added to their server also - but they do not know....

f=image is not available at layer level - f=html is available with the
layer 0 - that's why ouputformat not supported for this request
please have look at the capabilities
capabilities example you can find with
is a correct request
in the url parameter it should work
so what does your arcgis service answers compared to arcgisonline
service for capabilities?
because of the 400 i think that this is not the correct onlineresource of your arcgis service
is a typical capabilities request - that most clients send - this should work with your url
