Okhttp 在代理连接关闭后发送 http 请求

Question

我正在通过代理传送我的请求，它似乎每 10-15 秒关闭一次连接。因此，如果客户端请求一个网站并且需要一些时间，连接可能会关闭，因此 okhttp 库会抛出 "unexpected end of stream"。即使连接已关闭并且库抛出该异常，服务器已成功接收到请求，但客户端无法检查答案。如果我尝试在没有代理的情况下请求相同的 url 我没有问题并且我成功收到了答案。在这里你可以看到它的wireshark： wireshark capture

在照片的最后你可以看到客户端在 19:27:54,980 发出的请求，然后在 10 秒后，客户端收到了 FIN tcp 数据包。所以在那之后 Okhttp 抛出这个异常：

java.io.IOException: unexpected end of stream on Connection{m.apuestas.codere.es:443, proxy=HTTP @ /185.163.232.127:58542 hostAddress=/185.163.232.127:58542 cipherSuite=TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA protocol=http/1.1}

不是服务器关闭了连接，因为我一直在同时向不同的服务器发出不同的请求，突然同时连接被关闭了。所以我的问题是，即使连接被代理服务器关闭，是否有办法接收该答案？

代理服务器提供商每 10 秒断开一次连接。
