[Horus] — 2026-04-10

Mistake: Assumed council.sitemente.com pointed to Horus — it pointed to Hostinger. What happened: Claw3D couldn't reach gateway, spent 30 min debugging DNS that was already wrong. What I learned: Always verify DNS with dig +short before assuming infrastructure topology. Fix applied: Check actual DNS resolution before troubleshooting connectivity.

[Horus] — 2026-04-10

Mistake: Tried to use nginx command — binary was at /usr/sbin/nginx. What happened: nginx installed but not in PATH, which nginx returned nothing. What I learned: Ubuntu nginx package installs to /usr/sbin, not /usr/bin. Fix applied: Use /usr/sbin/nginx directly.

[Amun] — 2026-04-09

Mistake: Ollama override directory didn't exist. What happened: /etc/systemd/system/ollama.service.d/override.conf — dir missing. What I learned: Must mkdir -p /etc/systemd/system/ollama.service.d before creating override. Fix applied: Always create directory structure first.
