Original GitHub issue: https://github.com/karakeep-app/karakeep/issues/466

I setup hoarder on my Synology NAS but am seeing crawler issues whenever I bookmark anything. I've set them up as a Project in Container Manager on Synology using the compose.yml file given in the Installation guide.

Not sure if there is some extra setup I need for getting this to work on Synology.

I figured out that I needed to allow my docker container network bridge ip range through the Synology firewall. Seems to be working now
