networking – ORA-12520: TNS: Listener could not find the available handler for the requested server type

I'm trying to connect to a remote database with sqlplus, but not only can connect to a specific database server. I can connect to other server databases. I have checked the listener services, tnsping, tnsnames.ora and other ways. Able to not connect with username as sysdba.

sqlplus username @ service

oracle – TNS-12560: TNS: Protocol adapter error

I can not access remote because of my listener error. I checked all the configuration files that are listener.ora, tnsanmes.ora, and sqlnet, but I have not found any missing configuration.
Below is my listener.ora

SID_LIST_LISTENER = (SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D: app Administrator product 11.2.0 dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS = ONLY: D: app Administrator product 11.2.0 dbhome_1 bin oraclr11.dll")
))

LISTENER = (DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = STCDB) (PORT = 1521))
(ADDRESS = (PROTOCOL = IPC) (KEY = EXTPROC1521))
))

ADR_BASE_LISTENER = D: app Administrator

Here is tnsnames.ora

ORACLR_CONNECTION_DATA = (DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC) (KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
))

ORCLAMS = (DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = 10.15.192.18) (PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orclams)
))

Actually, my Oracle server worked normally before changing the IP address of the server from 10.15.193.18 to 10.15.192.18. So I changed the new IP address tnsnames.ora, then Oracle did not work properly

Thank you in advance.
