本地windows7没有出现过这个问题，jdk17.0.8
服务器CentOS Linux release 7.9.2009 (Core) 上出现了这个问题。jdk17.0.2

proxyee 1.7.6

复现步骤
curl -i -x ip:port -U x:x https://www.baidu.com 第一次可以正常请求

curl -i -x ip:port -U x:x https://www.google.com 第二次 异常
curl: (56) Recv failure: Connection was reset

curl -i -x ip:port -U x:x https://www.google.com 第三次报以上错误
curl: (56) Proxy CONNECT aborted

补充，局域网内没有问题，使用公网IP代理就有这个问题。

Supplement, there is no problem in the LAN, but there is this problem when using the public IP proxy.
