Hello Geoserver friends,
does anyone have any tips on how to navigate/debug this issue?
I have a docker installation of Geonode 4.2.x + Geosever.
I must have tweaked some of the security settings at some point of time. However everything seemed to be working fine. And it seems like spontaneously vector tiles stopped working.
here is the error trace from the geoserver log
when i make a request to WMTS
