How can I troubleshoot issues with dynamic registration?
Listener registration in the database can be traced with:

alter system set events='immediate trace name listener_registration level 3';


Disable tracing when it is not needed anymore:

alter system set events='immediate trace name listener_registration level 0';


PMON registers to addresses defined in local_listener and remote_listener parameters. If you have an invalid address defined there, then it will not be able to register the instance in the listener.

If you have nothing defined there, then it tries to register on the local machine using the default 1521 port.

You could also try to set your local_listener as:

alter system set local_listener='(ADDRESS=(PROTOCOL=tcp)(HOST=10.10.13.134)(PORT=1521))';
alter system register;
