Personalized map

Marka year ago

I have been able to load my test XYZ file in QGIS from my own webserver without problems. In Traccar I am getting errors still:

Error: Could not load image because of The source image could not be decoded.. Please make sure to use a supported image type such as PNG or JPEG. Note that SVGs are not supported.

What am I still overlooking?
