ERROR: HTTP: Failed binding socket to port 55414 and 55413

Hello, I need help, I have a ubuntu server 20.04 served, it indicates an error in the socket 55414 and 55413. When connecting to the clients, only a first copy was made, then I no longer perform. The firewall already has the port exclusions.
