Hi,
> Why? What should i do to solve this question?
There may be a problem with the destination port.
Please execute the following command.
$ ryu-manager --verbose --ofp-tcp-listen-port 6653
If Ryu can connect to the OVS, the following log is output.
------------------------------------------------------------------
$ ryu-manager --verbose --ofp-tcp-listen-port 6653

------------------------------------------------------------------
Do you use any version of the Ryu?
If the version of Ryu you are using the old,
Ryu might not correspond to a port numbers 6653.
If possible, please try to install the latest version of Ryu.
If still no good.
please execute the following command,
make sure that the port is not LISTEN to other processes.
$ netstat -apn | grep LISTEN
Thanks,
