So I managed to connect to the Rpi using CLI (MobaXterm).

I did two tries, typing “yunohost tools postinstall”:

First try, using a domain that I own:

“Error message:  
Error: The domain already exists”

It seems the device is somehow registered with that domain, but the postinstallation is not complete anyway.

Second try, using a [nohost.me](http://nohost.me) domain that I believe is not taken:  
"Error: Unable to reach DynDNS provider [dyndns.yunohost.org](http://dyndns.yunohost.org): either your YunoHost is not correctly connected to the internet or the dynette server is down.  
"  
But I don’t think it is down!

I’m considering reflashing the image and going straight for the CLI.

BTW, I found one other similar support topic here describing similar errors, however here the CLI solved the issue:
