Reverse Proxy on Apache/Ubuntu

Question

i need to setup reverse proxy with Lets Encrypt for multiple app servers. I installed Webagte server:

Ubuntu Server 18.04 LTS
Apache 2.4

Apache runs OK and "first" page show. But when i put this:

<VirtualHost *:80>
ServerAdmin "my@mail.tld"
ServerName "app1.mydomain.tld"
DocumentRoot "/var/www/app1.mydomain.tld"
ProxyPreserveHost On
ProxyPass "/.well-known/" !
ProxyPass "/test-broker/" !
ProxyPass "/" "http://192.168.1.21:20000/"
ProxyPassReverse "/" "http://192.168.1.21:20000/"
</VirtualHost>

to file /etc/apache2/sitest-enabled/000-default.conf and open my browser page i get ERR_CONNECTION_REFUSED.

Checklist:

/var/www/app1.mydomain.tld exist.
http://192.168.1.21:20000/ work.
app1.mydomain.tld in DNS exist and is pointed to webgate server.
a2enmod proxy enabled.
a2enmod proxy_http enabled.
a2enmod proxy_ajp enabled.
a2enmod rewrite enabled.
a2enmod deflate enabled.
a2enmod headers enabled.
a2enmod proxy_balancer enabled.
a2enmod proxy_connect enabled.
a2enmod proxy_html enabled.

Thanks for any help.

Could be a client problem. Can you try it from another browser and or another machine? Can you reach it with `curl` over command line? https://downforeveryoneorjustme.com/ — jschnasse, Mar 31 '20 at 14:23

The virtual host you have there will only get used on HTTP traffic, so the server is refusing a connection from browser on standard HTTPS port 443.

You will need an additional virtual host for 443 <VirtualHost *:443> which has ssl config included as per Apache SSL HowTo.
