Fixed

GeoIP Backfill Infinite Loop on Startup

• Application startup could hang indefinitely when IP addresses could not be resolved by the GeoIP database
  • The backfill loop fetched rows with country_code IS NULL, but only updated them when a valid country was returned — unresolvable IPs were never updated and re-fetched forever
  • Now assigns fallback values (ZZ / Unknown) for any IP that cannot be resolved, ensuring every row is processed exactly once
  • Thanks to @P7aM5qzEddT66lE for reporting and submitting the fix (#58)

Startup Crash with DEBUG=true

• Application crashed immediately on startup when DEBUG=true was set in environment variables (#57)
  • Engine initialization now conditionally applies pool_size/max_overflow only when using the standard connection pool

Settings Page Freeze (~30 Seconds)

• Settings page could hang for up to 30 seconds, especially after the application hadn't been accessed for several days
  • Root cause: the GET /api/settings/info endpoint made a synchronous external HTTP call to MaxMind's license validation API on every page load — if DNS cache expired or the network was slow, TCP connect timeout could block for 30+ seconds
  • MaxMind license validation is now fully on-demand: the settings page no longer checks license validity automatically. Instead, a "Validate" button lets users check when they want to
  • Added POST /api/settings/maxmind/validate endpoint for on-demand validation

Changed

MaxMind License Status

• Validation results are now persisted in the database (system_settings table) and survive page refreshes, container restarts, and re-deployments
• Clearing MaxMind credentials properly resets the status back to "Not checked"

MaxMind Settings UI Improvements

• "Validate" button for MaxMind license validation now appears only when credentials are configured (not when empty)
• "Repair" button added for corrupted GeoIP databases — automatically re-downloads and re-validates database files when "DB Corrupt" status is detected

Fail2Ban IP Lists Redesign (#51)

• Added Active Bans list showing all currently banned IPs with visual distinction between permanent and temporary bans
  • Permanent bans (red badge): IPs from the denylist — cannot be unbanned directly, must be removed from the denylist
  • Temporary bans (amber badge): dynamically banned by Fail2Ban with remaining ban time displayed and an "Unban" button
  • IPs queued for unbanning show a "Unbanning..." status indicator
• Simplified IP Lists layout from 3 columns to 2 (Allowlist + Denylist) with the Active Bans section below
