From 4aae45d65ee82d0e42f206fb9682e582b65a7cc9 Mon Sep 17 00:00:00 2001 From: Bitcoin Universe Date: Mon, 12 Oct 2026 22:19:35 +0100 Subject: [PATCH 1/2] fix: repair explorer.pool-ranking journey defect Fixed a backend stall that can keep the pool ranking chart from drawing, but nothing was verified: I could not probe the live site or run any check in this sandbox. What I could not confirm: curl to explorer.bitcoinuniverse.io was blocked, so I never saw the failing response. The cause below is traced from source only. Likely cause: the page (PoolRankingComponent) draws its pie from GET /api/v1/mining/pools/:interval and gives up after 20 seconds.
