Can't start Ravada VM with IPv6 only.

[ph0llux]

Describe the bug I've tried to start a virtual machine using Ravada on an IPv6-only server. If I try to start the machine, this error occured.

To Reproduce Steps to reproduce the behavior:

1. replace the appropriate listener at /etc/rvd_front.conf with listen => ['http://[::]:8081']
2. Login to Ravada web
3. create a virtual machine (e.g. Windows 11)
4. Try to start the machine

Expected behavior Start the virtual machine

Server (please complete the following information):

Client (please complete the following information):

• OS: Fedora 38

Additional context There is an additional error log message:

The address fd00:fffe::2 is the appropriate address of my Fedora client.
