Can't ping local IPv6 on Ubuntu 22.04.1 LTS with Netplan

I have truly bizarre issue. I setup my network on VPS, according to guide, with Netplan. Everything works fine for internet connection, but I can't seems to be able to ping local IPv6, IPv4 works as intended.

Here is my netplan script:

network:
  version: 2
  renderer: networkd
  ethernets:
    ens18:
      match:
        macaddress: 00:50:56:48:99:ef
      addresses:
        - 109.123.254.106/20
        - 2a02:c206:2107:4459:0000:0000:0000:0001/64
        - 2a02:c206:2107:4459:0000:0000:0000:0002/64
        - 2a02:c206:2107:4459:0000:0000:0000:0003/64
        - 2a02:c206:2107:4459:0000:0000:0000:0004/64
      routes:
        - to: 0.0.0.0/0
          via: 109.123.240.1
          on-link: true
        - to: default
          via: "fe80::1"
          metric: 1
          on-link: true
      nameservers:
        search: [ invalid ]
        addresses:
          - 161.97.189.51
          - 161.97.189.52
          - 2a02:c206:5028::1:53
          - 2a02:c206:5028::2:53

So if I want to do sudo ping6 2a02:c206:2107:4459::1 or sudo ping6 -c 5 -I ens18 2a02:c206:2107:4459::1

It isn't doing anything, it's just stays and then it says

5 packets transmitted, 0 received, 100% packet loss, time 2033ms

I never really had to setup a IPv6, however I need those to be able to reach the local network. The communication with outside IPs on internet works fine and I can ping it from my PC fine as well.

So what can I do for that?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
