Meaning

Increase the timeout (Http::timeout(60)), set a connect timeout, retry with backoff (->retry(3, 200)), and check the remote API's health and network egress (firewalls, DNS). For slow endpoints dispatch jobs instead of blocking web requests.

Common causes

  • Remote API slow or down
  • Default 30s timeout too low
  • Outbound firewall/DNS issues
  • Large response on slow link
  • IPv6 route problem

⚡ Quick fix

  1. Http::timeout(60)->connectTimeout(10)->retry(3, 200)->get($url)
  2. Test from the server: curl -v URL
  3. Move slow calls to queued jobs

Detailed fix by platform

Linux

  1. curl -v --max-time 30 https://api.example.com/health

How to diagnose

  1. Timeout — Configured value?
  2. Remote — Reachable from server?
  3. Retry — Backoff?
