Replit api

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

  1. Default HTTP timeout too short (often 0 = infinite)
  2. External API very slow or unreachable
  3. Network/DNS resolution slow from Replit
  4. API missing required authentication headers
  5. 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.
