External API Calls Timing Out on Replit
Your app hangs when calling external APIs. Requests to third-party services timeout without response.
Network latency and Replit's resource constraints cause slow API calls.
Error Messages You Might See
SocketTimeoutException: Read timed out
java.net.ConnectException: Connection refused
Connection timeout after 30000ms
Common Causes
- Default HTTP timeout too short (often 0 = infinite)
- External API very slow or unreachable
- Network/DNS resolution slow from Replit
- API missing required authentication headers
- Rate limiting causing delays
How to Fix It
Set explicit connection and read timeouts (5-10 seconds). Use RestTemplate with HttpClientBuilder or WebClient. Implement circuit breaker pattern with Resilience4j to fail fast. Test API connectivity in Replit shell with curl. Consider caching API responses to reduce calls.

Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.
