change of IP adress

I recently had to change the IP adress on my PC running LMS, subsequently I am unable to get my Slimdevices to connect to it, when I run the Info from the control panel app I still see the OLD IP address, is there any specific change I need to make, fo the new IP address to take effect ?

Server version 7.9.3 on wired connection
players Slim 3 and Duet all on WiFi connections

any advice would be appreciated
Thank you
