Browser error I get:
ERR_SSL_PROTOCOL_ERROR
Command-line error I get (in case the additional info is useful):
$ wget -O - https://xxxx.com
--2017-02-12 19:09:19-- https://xxxx.com/
Resolving xxxx.com (xxxx.com)... 68.168.108.xxx
Connecting to xxxx.com (xxxx.com)|68.168.108.xxx|:443... connected.
OpenSSL: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol
Unable to establish SSL connection.
Comments and related settings:
--- The SSL (same certificiate) does work with the Webmin control panel; That is to say that https://xxxx.com:10000 works fine
--- Webmin Configuration > SSL Encryption > Enable SSL? = YES
--- Webmin Servers > Apache Webserver > Global configuration > Configure Apache Modules = SSL is enabled
--- Virtualmin System Settings > Features and Plugins > SSL website = CHECKED/YES
--- Virtual Server > Server Configuration > Manage SSL Certificate = the SSL certificate has been added here as well; the same SSL certificate as added to Webmin in fact.
Operating system: Ubuntu Linux 16.04.2
Webmin version: 1.831
Virtualmin version: 5.05
