Hardware: Contabo VPS YunoHost version: 4.2.5.2 I have access to my server : SSH and browser Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
Description of my issue
Port 8095 appears to be unavailable even if my server provider (Contabo) tells me it is open and I clearly see it is in the list of opened ports in the Yunohost firewall.
You are not the first one reporting this (cf. here for example). I think it is a bug/oversight of the diagnosis which only tests TCP, or reports an error even if we only want it open in UDP.
The Wireguard interface appears to be ok and I can add tunnels. Nevertheless, it does not work. Unfortunately, I have really no idea how to configure WireGuard, hence I do not know if this is due to the port or to something I should have done and I did not.
I did not perform any command via SSH as internet guides pointed out, since I feared to interfere with Yunohost-made setup. Should I? Could you point me to some 101 basic tutorial compatible with the Yunohost installation?
You should see the peers too. Have you created devices in the UI? If so, can you check that they are listed in /etc/wireguard/wg0.conf? (Do not share its contents, or hide the private keys )
