Hardware: kvm YunoHost version: 11.2.11.3 I have access to my server : all Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
I have the same problem. Error message from the diagnosis that my server cannot be reached via IPV6. But it is! Not only in theory, but also in practice.
Well… not really.
Now the diagnosis shows me that there is no IPV4 connection and the problem with the missing IPV6 connection is only displayed as a warning. So it seems that something is still not working properly (in the diagnostics… my system is otherwise running smoothly).
