Cannot start a server after first pritunl installation

Hi,

I have installed Pritunl in an Almalinux 9.2 machine (VPS by a hosting provider). I have connected to the web services to create an organization and user associated with it. But after I create a server, it fails to start. In the logs I have the following:

[guarded-fields-9467][2023-06-01 18:12:33,128][ERROR] Failed to get IPv6 routes

I have troubles in understanding this error and I haven’t found something somehow related - neither in this forum nor anywhere - to at least try something useful.

The server will need to have IPv6 enabled even if IPv6 isn’t used.
