Roundcube Community Forum

Hi all,

i use Roundcube on a Proxmox Container with Debian / Testing a long time. Now aftern an upgrade to RC 1.6.9 works my Reverse Proxy Configuration not more.

When i call the local ip from the roundcube host with my browser works all as before after the upgrade, if i will connect over the proxy server to my internal roundcube host comes after the login an error message with denied access.

I use apache on both maschines (reverse and roundcube host)

What is the diffrent between these both versions with using reverse proxy?

My local config:
<VirtualHost *:443>

I'm not certain about this but have a look at the `request_path` config var. From the changelog:

QuoteAdd workaround for using Roundcube behind a reverse proxy with a subpath: 'request_path' option (#8738, #8770)

These are the linked issues:

Thank you @JohnDoh

Now it works with adding:
$config['request_path'] = '/';in my config.inc.php
