Error Adding a new server to the cluster version 118.0.4

If I try to add a nameserver to the cluster, doing the entire procedure as per the documentation, it gives me this error

The reverse trust relationship could not be established from the remote server to this server.
You must log into the remote server and manually add this server using the “DNS Cluster” interface there if you want the other server to access this one.

In the log I find these errors

Cpanel::NameServer::Remote::cPanel: Unable to sync zones: on the remote server [] (Server Error from xxxxxxxxxxxx: 403 Forbidden Access denied)
You must set a host to connect to. (missing 'host' and 'ip' parameter)

If I try to reconfigure the Remote cPanel & WHM DNS host field: it is empty

The webserver version is 118.0.4
The DNS server version is 116.0.14

You must set a host to connect to. (missing 'host' and 'ip' parameter)
