Unfortunately this is not a Traefik issue but a Silverbullet issue. Essentially, the web server doesn’t support a subpath and instead assumes that it is at the root - see https://github.com/silverbulletmd/silverbullet/issues/794 for details.

You can try hosting it from a different subdomain or port instead.

Looks great!

This would be great! I would rather a steady feed of memes than multiple trickles.

This is most likely the issue. Maybe just measure HTTP response times instead?
