What type of hardware are you using: Old laptop or computer
What YunoHost version are you running: 11.1
How are you able to access your server: The webadmin
Direct access via physical keyboard/screen
Are you in a special context or did you perform specific tweaking on your YunoHost instance ?: no

Describe your issue

  1. new installation working with main domain: nohost.me
  2. access from another pc, and run diagnosis
  3. the first warning is: This server has no working ipv6。
  4. On the server, run
ip a

There is ipv6 address for my network interface.
Run

hostname -I

only IPv4 is displayed.

How could I have an IPv6 when I run

hostname -I

and get rid of the diagnosis warning?

no real log

What kind of IPv6 address ? Usually your network interface may have at least a local-only IPv6 …

same goes for hostname -I probably

The real test to verify ipv6 connectivity is to query an outside server using ipv6, for example : curl https://ip6.yunohost.org

Thanks.

curl https://ip6.yunohost.org

returns

curl: (7) couldn't connect to the server

while

ping -c 3 www.yunohost.org

is fine, and

ip address

gives me both inet (ipv4) and inet6 (ipv6).
What could be my problem?

One final test is to open https://ip6.yunohost.org on your PC on the same network as the server.

If it fails to open too, you simply do not have an IPv6 attributed by your ISP. You may Ignore the warning from the Diagnosis. A cleaner way is to select “IPv4 only” in the Network section of the Other category of the YunoHost settings.

Thank you. I understand.

I will try to check if I can get IPv6 from the ISP.
