Hello,

I tried to follow the excellent idea/tutorial by @beat to make a redirection from my domain to a specific port to a docker container.

Everything seems to work well on the docker side, as using myip:3000 sends me to the service.

My first step was to replace the virtual host section of my domain with beat’s snippet. (and changing the values)

After doing that, when I go to configure website, I can’t access the file anymore, it looks like that I’m on the For default server page instead on being on my virtual server. So there is no more an option to edit my apache conf file. (However checking through the terminal, I can see that the file is still here)

<VirtualHost 192.168.1.17:80>

    RequestHeader set X_FORWARDED_PROTO 'https'
    RequestHeader set X-Forwarded-Ssl on
</VirtualHost>

When I try the https://mydomain.com, I am told there is a certificate anomaly by the browser and if I continue, I get redirected to the first virtualhost of my server.

Thanks a lot for any help !

Cheers,

Hello,

You need to configure a balancer and also skip on SSL certificate check, for example:

<Proxy balancer://path1>
    BalancerMember https://127.0.0.1:3000
    SSLProxyCheckPeerName off
    SSLProxyCheckPeerCN off
    SSLProxyCheckPeerExpire off
</Proxy>
ProxyPass /path1 balancer://path1

Although, we recommend using Virtualmin Pro to do it for you with Proxy Paths feature.
