Fixes Spider freezing your feed: productive but short-lived upstream connections no longer escalate into multi-hour reconnect blackouts. Also fixes the relay being capped at 10 connections behind the StartOS reverse proxy by no longer limiting connections per IP, matching how nostr-rs-relay and strfry are packaged.',
