<span style=" font-size:10pt;font-family:sans-serif">I have configured
an OSM WMS with MapProxy. The yaml file is listed below. The WMS works
for example in QGIS. In other clients, however, I get the error "Request
too large or invalid BBOX".</span>

<br><span style=" font-size:10pt;font-family:sans-serif">:</span>
<br><span style=" font-size:10pt;font-family:sans-serif">The problem seems
to be the parameter Tiles = true. The parameter is set via the clients.
If I change the value to false I get a result (here a png). The BBOX in
the WMS request is within the defined BBOX in the yaml and the data. I
haven't found any ways to solve the problem so far. What else can help?
