Want to unify OpenAI, Claude, Gemini, DeepSeek, Qwen, Doubao and other models behind a single API entry point? This article covers when a self-hosted AI API gateway on a VPS makes sense, how to choose between One-API and New-API, Docker Compose deployment, channel configuration, key management, rate limiting, logging and a security checklist.
Cloudflare Tunnel lets web services on a VPS avoid exposing public ports directly: cloudflared actively connects out to Cloudflare, and Cloudflare then reaches back to your local service. This article explains which scenarios it suits, how to deploy it, how to bind a domain, how to protect the admin backend with Access, and how to troubleshoot common issues such as Inactive status, 502 errors, and the origin still being directly reachable.
After you connect to a VPS over SSH, the session drops after a while, or you see Broken pipe, Connection reset by peer, or Operation timed out. This is usually not a wrong password but idle timeout, network jitter, NAT reclamation, sshd keepalive, or a local network problem. This article gives troubleshooting and fix commands across three layers: client, server, and network path.
SSH suddenly stops connecting after you enable UFW. Usually the server isn't broken — the problem is the SSH port, the cloud firewall, or rule ordering. This article covers four situations — still connected, locked out, console-only access, and rescue mode — with copy-paste troubleshooting and recovery commands.
When your VPS website loads slowly but bandwidth isn't saturated and CPU isn't high, check TTFB first. This article walks through the browser waterfall, curl timing, Nginx upstream_time, PHP-FPM, database slow queries, DNS/TLS, and Cloudflare origin fetch in order.
When a Docker container on a VPS keeps restarting, it's usually not Docker itself that's broken, but rather the application failing to start, missing configuration, port conflicts, failed health checks, or OOM. Troubleshooting in the order of logs, exit codes, restart policy, resources, and dependencies lets you quickly pinpoint the cause.
When your VPS shows SSH Permission denied, don't rush to reinstall the system. Work through authentication method, username, key permissions, sshd config, cloud console, and Fail2Ban in order, and you can usually pinpoint the cause quickly.
Nginx running doesn't mean it's secure. Common risks on a VPS include outdated TLS configuration, missing security headers like HSTS/CSP, directly exposed origin IP, no request rate limiting, unprotected admin paths, and error logs nobody reads. This article gives an Nginx security hardening checklist suited to small sites and self-hosted services, in deployment order.
n8n is an open-source workflow automation tool you can install on your own VPS to replace Zapier. This article walks you through deploying n8n on a VPS with Docker Compose, configuring HTTPS, running your first automation workflow, and connecting DeepSeek AI for intelligent automation.
