Aveva Intouch 2023R2 : License manager problem

Hi 

I have a problem with the license Intouch 2023R2 . I could not install it online and offline, it show error "License manager cannot to the License Server on port 55555." even i turn off the firewall already. I uninstalled it and then installed it again. It's not work. What can I do next? Help me please.
