Operation timed out
Quick Answer
Increase the timeout or implement retry logic with exponential backoff.
What this means
An I/O operation did not complete within the configured timeout period.
Why it happens
- 1Network latency exceeds read/write timeout
- 2Server is overloaded and not responding
- 3Incorrect timeout set too low
Fix
Set a reasonable timeout
Set a reasonable timeout
use std::net::TcpStream;
use std::time::Duration;
let stream = TcpStream::connect("host:80")?;
stream.set_read_timeout(Some(Duration::from_secs(10)))?;
stream.set_write_timeout(Some(Duration::from_secs(10)))?;Why this works
Configures per-operation deadlines so calls never block indefinitely.
