連接錯誤：連接嘗試失敗，因爲連接方在一段時間後沒有正確響應

Question

我正在開發一些使用Steam API的python軟件。我使用Flask來運行和測試python代碼。一切都進行得膨脹，但現在我得到這個錯誤（我沒有改變任何代碼）：

('Connection aborted.', error(10060, 'A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond'))

我不知道爲什麼這個錯誤就要到了，由於代碼工作完全正常，突然錯誤出現了，我沒有改變任何代碼或者我的電腦或者Flask。

代碼：

我想有一個解釋的錯誤意味着什麼，爲什麼發生這種情況。提前致謝。我非常感謝幫助。

Answer 1

那麼，這是不是燒瓶錯誤，它基本上蟒蛇套接字錯誤

爲10060似乎是一個超時錯誤，是否有可能在服務器中接受，如果網站在瀏覽器中打開很慢， ，那麼你的瀏覽器有可能有更高的超時閾值？

嘗試增加請求時間在request.GET中（）

如果遠程服務器也是在你的訪問，則： 你並不需要綁定套接字（除非遠程服務器有進入插座的預期） - 這實際上是連接的一個要求，這是非常罕見的。

Answer 2

我想這是因爲steamcommunity的服務器不穩定或者一些網絡問題..

通常情況下，你不能修復的淨shake.But那裏是仍然有一些方法可以幫助ü。

首先，當你發現網絡錯誤時，你讓你的線程睡眠一秒鐘，然後再試一次！其次，我建議你使用Flask-Cache，例如緩存60秒，這將有助於減少http請求。

Answer 3

根據我的經驗，那些「關聯方在一段時間後沒有迴應」，特別是當以前使用的相同代碼通常與MTU大小有關時。通常你應該只是determine the maximum MTU size（不要忘記添加28個字節，如鏈接中所述），然後你可以在你的客戶端計算機change the MTU size。
