Cura not finding my printer

[chguillarme 0]

Hi all.

I have an issue. I installed my newly received ultimaker 3 last friday. On first launch I spent hours understanding calibration but now it's done (first job printed by USB is great)

Now that I can print, Cura doesn't seem to work anymore : that's why first job was printed through USB.

When I installed everything, Cura was working and I could connect to the printer (but couldn't begin a print has calibration was not working). After the week end, nothing seems to work : Cura doesn't find the printer anymore on my network.

The strange thing is I can connect to the printer thorugh the web stream in Chrome or another browser, but Cura keeps telling me the printer is not connected in the manage printers tab.

I put the IP adress in Connect via Network but here I always have "the printer at this adress has not yet responded."

I deleted Cura's files, I uninstalled/reinstalled Cura. Nothing changed.

Any idea from where my issue may come ?

Thank you for your help.
