Ok, it turns out I get the old ui when I use os_addr, and get the new one when I use os_addr:8080. (os_addr is 192.168.0.43 in this case)
When I try to access 192.168.0.43/su or 192.168.0.43:80/su, I get
This site can’t be reached
192.168.0.43 refused to connect.
But, I can access the web page at 192.168.0.43:8080/su
Should I do something to get rid of whatever makes the old ui used at 192.168.0.43:80? How?
