TCP flood, SYN flood and cURL errors: understanding attacks that disrupt connections
A network and gaming guide explaining how TCP floods, SYN floods and cURL errors affect APIs, web services, FiveM, games and protected IP transit decisions.
Gaming connectivity and protection guides.
A player timeout, a failed server-information request and a stalled loading screen can involve different protocols and components. Start with the failing stage before changing a firewall or assuming a DDoS attack.
The library also contains Rust and Garry’s Mod diagnostic guides. Their presence does not imply a dedicated Peeryx application-filtering offer. The specialized public offers currently cover FiveM and Minecraft Java.
Suggested reading order
Check the service and the endpoint
Confirm the process is listening, the public endpoint is correct and a known-good client can reach it. Separate a service failure from a failure affecting one access network or route.
Follow the connection sequence
For FiveM, distinguish HTTP metadata and downloads from UDP information and game transport. For Minecraft, distinguish the public proxy from the backend and its forwarding trust configuration.
Validate the protected delivery
Keep origin access restricted to the intended path, test legitimate joins and reconnects, and compare latency on the same route. A proxy changes the path; its behaviour needs a real end-to-end check.

UDP flood on a game server: why classic protections filter badly
A network and gaming guide explaining why UDP floods against game servers often bypass generic DDoS protection, and how to design cleaner mitigation.
Rust server timeout: how to tell whether it is a DDoS, network or server configuration issue?
Complete technical guide for rust server timeout: packet loss, unstable routes, firewall, Steam ports, Rust server configuration, hoster filtering and gaming Anti-DDoS.
Garry’s Mod “Connection failed after 6 retries”: network causes and DDoS protection
Complete technical guide for garry's mod connection failed after 6 retries: SRCDS ports, firewall, UDP 27015, Steam query, routing, hoster filtering, DDoS and Peeryx gaming protection.
Minecraft “Can’t connect to server”: diagnose DNS, ports, proxies and DDoS
Use the failed connection stage, logs and matched network observations to distinguish DNS, TCP listeners, forwarding errors, application load and attacks.
FiveM stuck loading: find the failing join stage
Separate resource downloads, server builds, loading-screen scripts and network failures with a staged FiveM diagnosis and a complete join acceptance test.
FiveM Reverse Proxy: how to protect your server without breaking UDP connections
Commercial and technical guide to fivem reverse proxy anti ddos: protect a FiveM server, keep UDP stable, hide the backend and avoid false positives that break player connections.
FiveM at OVHcloud: check the offer and the evidence
Distinguish OVHcloud network protection from its Game profiles, verify your server’s actual configuration and diagnose a FiveM incident before changing providers.
FiveM cURL error 56: diagnose the failed receive
Find which FiveM request failed, correlate client, proxy and server evidence, and distinguish a receive error from a timeout or a DDoS diagnosis.
FiveM getinfo failure: check the UDP connection path
Diagnose the FiveM getinfo retry failure, distinguish UDP information exchange from HTTP metadata and identify the failing endpoint before changing protection.
FiveM “Fetching info”: what to check first
A practical triage checklist for players and server staff: identify the stalled stage, save useful evidence and hand the incident to the right operator.
FiveM: prepare the network before opening a server
Map connection endpoints, validate a complete player journey and check access to the origin server.
Gaming proxies: separate relay delay from server response
Measure network detours, relay behavior and application load across comparable player journeys.
Minecraft DDoS protection: secure the proxy, backend and player path
Separate network floods from login abuse, secure Velocity or BungeeCord backends, and test real player connections before changing the public endpoint.
Gaming Anti-DDoS: why generic filtering is not always enough
Gaming needs Anti-DDoS protection built around sessions, latency, false positives and real protocol behaviour. This guide explains why generic filtering is not always enough and how to design a more serious gaming protection model.

Protect the public entry point without moving the host.
FiveM and Minecraft Java protection can relay traffic to an existing origin, subject to integration review. Confirm the protocol, origin reachability and access controls before changing the endpoint used by players.
