Description du problème:

Have you disabled ipv6 on your raspberry pi ?

Have you installed yunohost from raspbian or from yunohost rpi image ?

[gilles09]

installation from yunohost rpi image.
I don’t remember if i have disabled ipv6.
In fact my provider now use ipv6 only.
in my registrar dns i’ve no aaaa adresse.
With yunohost admin it was possible to show this address ipv6.
But i don’t how to obtain this address via ssh

But i don’t how to obtain this address via ssh

curl https://ip6.yunohost.org

[gilles09]

Curl don’t work with subdomain

admin@cayra:~ $ curl https://ip6.yunohost.org

Your ipv6 may be deactivated:

sysctl net.ipv6.conf.all.disable_ipv6

If it return net.ipv6.conf.all.disable_ipv6=1 configure it to 0

sysctl net.ipv6.conf.all.disable_ipv6=0
sysctl net.ipv6.conf.default.disable_ipv6=0

If it works, change permanently by editing the file /etc/sysctl.conf :

nano /etc/sysctl.conf
