Layer: pv_roof-top_pv_plants_2035 (gpkg: 113 MB)
Other point layers do work though.

We run into a gunicorn timeout here, when trying to fetch the corresponding url at https://egon.rl-institut.de/map/clusters/pv_roof-top_pv_plants_2035.geojson

Current solution: We decreased the number of PV plants by increasing the barrier to 0,13 MW (instead of 0,1) per plant.

We might still want to increase the gunicorn timeout. That can be done by adding --timeout 60 when running gunicorn.
We probably can simple change line 11 in /compose/production/django/start from
/venv/bin/gunicorn config.wsgi --bind 0.0.0.0:5000 --chdir=/app
to
/venv/bin/gunicorn config.wsgi --bind 0.0.0.0:5000 --chdir=/app --timeout 60
(current timeout is at 30s).

But it might be a better idea to investigate why the query take so long.
