who can tell me the reason will cause ros(www,80) invalid?
what you mean by invalid? where you see that message? maybe you are running transparent proxy?
ip services display all protocol,www is invalid,the text with red color shows,and i can not visit by web,as i know the log download by port 80,so the logdownload.exe does not works,reboot,it is ok ,run some hours,it is invalid again.
what version of ROS?
You should always try to upgrade in such cases. Maybe some package is corrupted, or some already fixed issue showed up
