## 🔑 Key Gotchas

| Area | Warning |
|---|---|
| **nginx / certbot** | Certbot corrupts configs — always inspect after issuance; check for duplicate `server_name` and missing closing braces |
| **NFS mounts** | Use `soft,timeo=30,retrans=3` — hard NFS can freeze Proxmox host |
| **DDNS script** | `/tmp/ddns_last_ip` cache persists at runtime; cleared on reboot |
| **WebSupport DNS** | Two separate management pages — missing the second caused an outage. DNS A record must exist before certbot can verify. Always update both pages. |
| **Gitea writes** | Always read file content before writing — writes replace entire file |
| **Proxmox kernel** | PINNED to `6.14.11-5-pve`. Do NOT unpin or upgrade without verifying NVIDIA 550 DKMS support first |
| **OpenRGB** | Uninstalled — SMBus interaction with ADATA XPG GAMMIX D35 poses hardware risk. Do not reinstall. |
| **Hairpin NAT** | Slovak Telekom router blocks hairpin — test external domains from mobile data, not LAN |
| **WebSupport API auth** | HMAC-SHA1 signed requests; `X-Date` header in `YYYYMMDDTHHmmSSZ` format; service ID is numeric `15056760` |
| **kocka-novinky.sk** | Wordfence blocks login — keep disabled. wp-config.php WP_SITEURL/WP_HOME hardcoded. Zen browser Content-Encoding issue — use Firefox/Chrome/Brave (not Zen). |
| **Paperless consume** | File watcher only detects new files — use `document_consumer --oneshot` for bulk imports |
| **LXC Docker** | Requires `--unprivileged 0 --features nesting=1` for Docker to work inside container |
