If you updated to the latest version - then remove "/rendered" from the URL.

See the release notes of v2.0: https://github.com/klokantech/tileserver-gl/releases

I have a (probably) related question: I noticed that the amount of RAM used by the tileserver-gl (running in docker container) increases by scrolling/zooming in the maps. I'm guessing the generated tiles are being cached in the the memory? I noticed that when the used RAM reaches the maximum available size (e. g. close to 4 GB if the server has 4 GB RAM), the tileserver crashes/hangs and the container needs to be restarted (btw: docker restart doesn't work for me, server is not reachable afterwards, i have to kill+start). The amount of RAM used never decreases over time, even if the server is idle for hours. Is this a known problem? Is there a way to prevent the continuous increase in RAM usage/crash?

I have the same issue as @mmuelder . Is there any update or plan to fix this issue?

Hi, tileserver-gl is based on expressjs and like any express application, it is not meant to be deployed as is as your application will work on a single process. To scale your tileserver-gl app you could try using something like p2m http://pm2.keymetrics.io for instance.

Any update on this issue? I have faced the same issue several times.
