TechHelpz (techhelpz.online) is a technical documentation site for people who run their own servers.
We publish direct, step-by-step troubleshooting guides for problems that come up on VPS and self-hosted setups, including:
- Control panels: aaPanel and CyberPanel
- Web servers and reverse proxies: Nginx, OpenLiteSpeed
- Mail: Postfix mail queue and delivery errors
- DNS and CDN: Cloudflare (SSL modes, Origin CA, DNS and TTL behavior)
- Databases and certificates: MySQL/MariaDB tuning, Let’s Encrypt renewal
How our guides are written
Every guide follows the same structure:
- Root cause diagnosis: why the error happens.
- Quick fix: the fastest way to get a service running again.
- Step-by-step resolution: exact file paths, commands, and configuration values.
- Edge cases: operating system versions, environment differences, and reasons a fix may not work for you.
We avoid filler and focus on information you can act on.
Who this site is for
System administrators, developers, freelancers, and small business owners who manage their own VPS or dedicated servers and need accurate answers quickly.
