@sharicov as you can see here Cloud Support · Issue #52 · YunoHost-Apps/netdata_ynh · GitHub they decided to switch off Cloud support voluntarily (not due to some technical problem I can help them solve). I did explain to them even if Cloud is built and enabled we do not send any data unless user explicitly Claims the node.
It is however up to them to make a decision as it is their package/project.
What you can maybe do is comment on that issue to let them know there is in fact user interest for Cloud support…
On this point I will mark this forum topic as resolved (as the only way to change this is talking with that package maintainers).
