vps使用脚本搭建hysteria2,一直速度都不错，偶尔会断几次网，一会就恢复了。
但是最近断开后一直不能正常使用，登陆vps查看hysteria2的log显示如下：
INFO server mode
INFO server up and running {“listen”: “:78135”}
INFO client connected {“addr”: “121.10.5.64:57309”, “id”: “user”, “tx”: 37500000}
WARN TCP error {“addr”: “21.10.5.64:57309”, “id”: “user”, “reqAddr”: “www.gstatic.com:80”, “error”: “dial tcp4 203.208.43.98:80: i/o timeout”}
INFO client disconnected {“addr”: “21.10.5.64:57309”, “id”: “user”, “error”: “accepting stream failed: Application error 0×0 (remote)”}
vps能正常ping通 www.google.com 和 www.gstatic.com
