I'm running Ubuntu 18.04 although couldn't I get it to work with Ubuntu 16.04 either. I'm running apache 2.4.29 and openssl 1.1.0g.

I'm trying to setup a reverse proxy that worked with Ubuntu 14, and getting these errors:

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 Port 443

From the log
[Tue May 29 09:14:36.494710 2018] [ssl:info] [pid 23700:tid 139947205977856] SSL Library Error: error:1408F10B:SSL routines:ssl3_get_record:wrong version number

when trying to connect via a browser

also getting these errors from the command line on the backend

openssl s_client -connect 1804-testserver.local:443
