How to reconfigure WebConsole Service to bind either the Linux Container's address or bind all addresses ?

As explained here: https://webchat.freenode.net/?channels=i2pd-dev

In Ubuntu 20.04 I have a working service that has webconsole:

Within Ubuntu 20.04 I created a Linux Container whose O.S. is Ubuntu 20.04 as well, that I called "ubuntuone"

I installed within this Linux Container the same service I2PD which seems working fine as well:

root@ubuntuone:/# systemctl status i2pd

root@ubuntuone:/#

The problem is I'm not able to use the WebConsole of this service.

This is the output of lxc info :

So, as far as I understand, I should be able to see the webconsole at 192.168.1.6:7070 address but I get:

This site can’t be reachedhttp://192.168.1.6:7070/ is unreachable.
ERR_ADDRESS_UNREACHABLE

Thanks to the LXD Expert: https://github.com/lxc/lxd/issues/9040 I discovered that I should modify the I2PD's WebConsole IP Address in order to bind the Web Console service to the Linux Container's address.

So, I tried to modify the address in etc/i2pd/i2pd.conf :

first to match the Linux Container's address:

[http]
## Web Console settings
## Uncomment and set to 'false' to disable Web Console
# enabled = true
## Address and port service will listen on
#address = 127.0.0.1
address = 192.168.1.6
port = 7070

and then to match all IP addresses:

[http]
## Web Console settings
## Uncomment and set to 'false' to disable Web Console
# enabled = true
## Address and port service will listen on
#address = 127.0.0.1
address = ""
port = 7070

but when I insert in the browser 192.168.1.6:7070 I get : ERR_ADDRESS_UNREACHABLE

This is the complete /etc/i2pd/i2pd.conf ` :

# Configuration file for a typical i2pd user
## See https://i2pd.readthedocs.io/en/latest/user-guide/configuration/
## for more options you can use in this file.

## Lines that begin with "## " try to explain what's going on. Lines
## that begin with just "#" are disabled commands: you can enable them
## by removing the "#" symbol.

## Tunnels config file
## Default: ~/.i2pd/tunnels.conf or /var/lib/i2pd/tunnels.conf
# tunconf = /var/lib/i2pd/tunnels.conf

## Tunnels config files path
## Use that path to store separated tunnels in different config files.

## Bandwidth configuration
## L limit bandwidth to 32KBs/sec, O - to 256KBs/sec, P - to 2048KBs/sec,
## X - unlimited
## Default is X for floodfill, L for regular node
# bandwidth = L
