<span style=" font-size:10pt;font-family:sans-serif">Hello,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">we have installed
Mapproxy on Ubuntu 22.04.2 LTS in our company, version 1.13.0.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">We provide a simple
wms with one raster layer.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">We also create
a seed configuration for this service which looks like this:</span>

<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Furthermore we
also installed the following versions:</span>

<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Does anyone have
an idea how to solve this or has anyone had this problem before?</span>
<br><span style=" font-size:10pt;font-family:sans-serif">It could also
be that the configuration is not quite right yet, but I suspect the problem
comes more from the libraries.</span>
