## TL;DR

The fix the maintainers recommend is to stop reusing connections: instantiate a new Client for each request (client = Client(timeout=(2, 20)); client.set_api_key(key)) instead of sharing one long-lived client.

## Steps

1. If you get intermittent mollie.api.error.RequestError with ReadTimeoutError against api.mollie.com, especially on Azure where the first attempt fails and the retry succeeds, the culprit is idle connection timeouts on the Azure side silently killing reused connections. The fix the maintainers recommend is to stop reusing connections: instantiate a new Client for each request (client = Client(timeout=(2, 20)); client.set_api_key(key)) instead of sharing one long-lived client. The original reporter confirmed this resolved it, and it had already worked for multiple other Azure users. Note the v3 client added its own timeout and retry mechanism, so if you just upgraded from v2 this behavior change can be the thing that surfaces the Azure idle-timeout problem.

## When to use

You are seeing this: If you get intermittent mollie.api.error.RequestError with ReadTimeoutError against api.mollie.com, especially on Azure where the first attempt fails and the retry succeeds, the culprit is idle connection timeouts on the Azure side silently killing reused... Use this skill when you run into "Intermittent Mollie API read timeouts on Azure: create a fresh client per request".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
