Connection refused to client

I am testing IotDB in standalone mode. The server works flawlessly whenever launched, but after a while client connections are refused either locally or remotely. I have the following errors logs:

Confignode logs:

I am hosting IoTDB on a VPS server with limited ressources (1GB ram). Although, when I run the start-stanadlone script the only ports that is open is port 6667, all other ports are closed. Any hints?

Thanks for your help.

Comienza con el script start-standalone y compara los logs de ConfigNode y DataNode alrededor de la primera conexión rechazada. Comprueba si los recursos limitados del VPS de 1 GB, los errores del procesador RPC del cliente o los puertos de servicio cerrados explican el fallo; se considera terminado cuando se haya identificado la causa y documentado una corrección o cambio de configuración reproducible.
