Four symptom branches: the process exits right after start (a quit line in autoexec.cfg, the bindip crash signature), missing from the browser list (query port not matching the panel allocation, the 12881 vs 13871 split), direct connect fails (using the query port as the join port, UDP-only firewall), version mismatch (1.0.1.0 moved to EOS anti-cheat and forced a wipe, the oldversion branch)
Use connect with the IP and the game port 12871 in the in-game F1 console (the official wiki marks it as the default port), or browse the OFFICIAL / COMMUNITY tabs. This site does not build a steam protocol connect link: AMP builds it from the query port, which conflicts with the wiki game-port reading and is unverified (D8)

Store pages for game 393420 and server 405100, the two official wiki mirror domains (fandom and wiki.gg), the uMod / Oxide framework and its plugins, Steam Workshop mods (loaded via loadmod) and the Oxide.Hurtworld source. hurtworld.com is now only a blog, last post 2020, with no hosting section
The same playerlootmode number means three different things across three sources (AMP seven values, survivalservers five values including an infamy tier, the Chinese panel only documents a 0 to 5 range). All three are shown side by side. The respawn estimate uses only the sourced 10 second base with a declared linear assumption (D13 / D17)
Pure arithmetic over the four decay convars (enabled, frequency, damage per event, how long a structure must stay unclaimed and unmodified): when decay starts, how many damage events, when it reaches zero. A two-value damage range is reduced to its midpoint and that is declared as a modelling assumption. Structure HP has no official table, so you must enter it
The developers never published dedicated-server hardware requirements; only client specs exist and cannot be reused. Every field is therefore editable, blank means not counted rather than zero, and the maths is a reproducible base plus per-player times players. The six upstream player defaults (20 / 16 / 50 / 60 / 120 / 150) are listed for comparison (D5)
The query port is derived as game port plus 10 following the OGP structural rule (12871 gives 12881), or set explicitly to a panel value such as 13871. The multi-instance step must be at least 11: with a step of 10 the next instance game port lands exactly on the previous instance query port, so this site refuses the whole plan instead of silently changing values (D1)
Four platforms (ufw / firewalld / iptables / netsh) and only two ports: game 12871 and query 12881. UDP only by default (A2S and game traffic are UDP in practice), TCP is an explicit checkbox (three upstreams register Both, no official statement, D3). Hurtworld has no management port, so no RCON rule can structurally appear in the output
Anonymous login installs 405100 (freetodownload=1) with a six-branch whitelist (public / oldversion / legacy / devtest / privatetest / whagwan); returning to stable writes -beta public explicitly. Backups emit copy commands only, preceded by a stop-the-server warning, and never a delete command. The systemd unit is off by default and requires a service user once enabled
Builds one -batchmode -nographics -exec string: the host arity drops between one, two and three arguments based on the map and save you fill in (the official wiki gives an example for all three, D4), the executable switches between Hurtworld.exe and Hurtworld.x86_64 per platform (D2), addadmin always emits a placeholder, and player counts pass two gates at 60 and 120 (D5)
Hurtworld has no ini file: autoexec.cfg holds one console command per line, executed line by line, where a failing line is only logged and does not stop the server (pinned by decompiled strings). This tool emits either the full file or a diff fragment from the same value function, and prechecks a file you paste for eight issue classes - flagging quit and bindip lines separately, the former being the top cause of a server that exits right after start
Commands are tiered by source: A for official announcements and the Oxide source, B+ for multiple independent transcriptions of the official wiki, B for upstream templates and a long-running community, C named and rejected. Includes what rcon actually is (an in-game forwarding command, not a network protocol - Hurtworld has no RCON) and counter-intuitive points such as kick taking a guid prefix rather than a SteamID64
