Drupal 8.x

I am using the group module in my site then installed webform_node and group_webform to be able to add my webform submissions to a group, but I want to add some submissions to their groups programmatically like I am doing with simple nodes.

In hook_ENTITY_TYPE_insert() I add nodes to their group, I want to do the same with webform but not sure if it can be simple since it needed integration module to work with group module.

I have some nodes that aren't visible to the non-identified user because it is specified in the view that I´ve created.

However, If you know the path of the node , it´s possible to access to this. I would like that a non-identified user can't see the node although he has the path.

I am researching recurring payment workflows.  I've set up the commerce modules and commerce-recurring (and a varienty of other commerce related modules). 

I successfully made one-time payments via Braintree and Authorize.net gateways.

I successfully set up subscriptions which reference the payment methods used for the one-time payments and these worked, more or less.  

I currently have a site with Drupal 8.9 (Composer).

I want to move my server. I recreated a new server and need to transfer my site to it.

How can I do this ?

I have prepared a roadmap but I don't know if this is the right method.

Destination

$ sudo unlink /etc/nginx/sites-enabled/www-example-com.conf
$ sudo systemctl restart nginx
$ ssh-keygen -t rsa -b 4096 -C ubuntu@www.example.com-migrate
$ cat /home/ubuntu/.ssh/id_rsa.pub

Hello,

I have a content type.

I like authenticated users only can view the nodes for the content type. Public are not allowed to view any nodes for that type.

People > permission > view content type > selected authenticated users. Anonymous users option is not selected. Public still can view.

Used this module. Rebuilt the permission. Did not work.
