I seem to have hit a strange issue on all lxd hosts (unsure when it started occurring!) but I cant seem to access images.linuxcontainers.org anymore.
Error: Failed parsing stream: Unable to fetch https://images.linuxcontainers.org/streams/v1/index.json: 403 Forbidden
When I try to add us.lxd.images, i get a 404, and readding the base gets me 403 again:
