If I try to go go Octopi.local the page won’t load and the browser can’t find the page to enter any login details.
The cura add in can see an octopi instance on the network but again can access the printer
The octopi still doesn't respond
Safari can't open the page
it doesnt seem to matter if I try to go via Octopi.local or the IP address that is seem by the router software and that is shown on the screen of the ender 3 pro that I have as 192.168.1.100
Seem to have now resolved the issue.
Have gone back to a wireless rather than wiredconnection.
many thanks for all of the suggestions and support but I'm now all good and connected
MAY give a different IP. My Asus router cleverly notices that the same device is connected by WiFi and wired at the same time, and gives the two interfaces the same IP address. It has a special symbol to tell you it has done so!
