Activepieces behind the reverse proxy

Hi everyone!

I have a problem with **activepieces**  ([https://github.com/activepie
ces/activepieces](https://github.com/activepieces/activepieces)) and
implementation of Apache reverse proxy

They provide explanation if Nginx is used as reverse proxy
([https://www.activepieces.com/docs/install/setup-ssl#setup-
nginx](https://www.activepieces.com/docs/install/setup-ssl#setup-
nginx))

I am using Apache web server as my reverse proxy and I have tried to
convert Nginx parameters to Apache like this

**Nginx**

    proxy_pass http://localhost:8080;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;

**Apache**

    RewriteEngine on
    RewriteCond %{HTTP:Connection} Upgrade [NC]
    RewriteCond %{HTTP:Upgrade} websocket [NC]
    RewriteRule /(.*) ws://127.0.0.1:28080/$1 [P,L]

    ProxyPreserveHost On

    ProxyPass / http://localhost:28080/ flushpackets=on
    ProxyPassReverse / http://localhost:28080/


        allow from all


    ProxyRequests Off

I can access activepieces backend, but if I add some (for example)
trigger to the Flow, I get this in the browser error console

​

[Errors in the browser console](https://preview.redd.it/40iwy441q76c1.

I would say that something is missing in the reverse proxy
configuration, but can't figure out what exactly

Any help would be appreciated!

Thank you all in advance!

So, to confirm, you set up the TLS cert? I can’t see you specifying it
in your Apache config.

Hi,

Yes, of course
The apache configuration is an extract of the complete virtual host
configuration, which is defined for the HTTPS version of virtual host.
All HTTP requests are also redirected to the HTTPS

Why not ask on the activepieces Github?

I did.

Seems like they are not very good with Apache reverse proxy
configuration
