I have a qgis server project in which I serve several tiffs. It used to work
fine but after updating to the latest version of QGIS 3 and QGIS 3 server it
When trying to connect via the Data Source Manager I get this error:
Today I copied the georeferenced tiffs into a new project.
When configuring QGIS server options I checked all tiff layers to be
published in the WCS section.
Now I can acces the WMS again and it renders as it should.
In the layerpanel there is just a warning that the legend could not be
rendered (probably because I put the tiffs in a group).
