我正在运行 Ubuntu 18.04，尽管我也无法让它与 Ubuntu 16.04 一起工作。我正在运行 apache 2.4.29 和 openssl 1.1.0g。
我正在尝试设置一个与 Ubuntu 14 兼容的反向代理，但出现以下错误：
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /testserver.
Reason: Error reading from remote server
Apache/2.4.29 (Ubuntu) Server at 172.16.0.140 Port 443
