httpx.ReadTimeout: Read Operation Timed Out

Why This Happens

httpx distinguishes connect timeout from read timeout. A read timeout means the connection was established but the server was too slow sending data.

The Problem

import httpx
client = httpx.Client()
response = client.get('https://slow-api.example.com')

The Fix

import httpx
client = httpx.Client(timeout=httpx.Timeout(10.0, read=30.0))
try:
    response = client.get('https://slow-api.example.com')
except httpx.ReadTimeout:
    print('Server too slow')

Step-by-Step Fix

1. 1

   Increase read timeout

   Set httpx.Timeout(connect=5.0, read=30.0).

2. 2

   Handle timeout exceptions

   Catch httpx.ReadTimeout for fallback.

3. 3

   Stream large responses

   Use client.stream() for large data.
