Error while using Keycloak with OracleDB

I’m using Keycloak version 15 connect with Oracle 12c, driver ojdbc8. Server have worked for a few month, but now it’s can’t connect to DB. Here is the error log:

non-wildcard server bind address or add client-mapping entries to the relevant socket-binding for the Remoting connector

12:35:46,255 WARN [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-3) SQL Error: 17410, SQLState: 08000

12:35:46,256 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-3) No more data to read from socket

12:35:46,278 ERROR [] (default task-3) Uncaught server error: javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: could not extract ResultSet

I really appreciate any idea how it happen. Thanks a lot!
