What happened? 

During the configuration of Prusa Connect on the Original Prusa Printers, an error can occur, and the printer shows the message "Registration to Prusa Connect failed due to: ~". In place of ~, a text with more details is displayed. 

Error name: Connect Registration Failed

Error code: #26401 (MK4S) #13401 (MK4) #27401 (MK3.9S) #21401 (MK3.9) #28401 (MK3.5S) #23401 (MK3.5) #31401 (CORE One)

How to fix it? 

Follow the instructions in the Connect Registration Failed guidepost, common to our printers with Buddy firmware, with more details on possible causes for this error and their solutions.

I'm getting the same "refused" response with no printer code being generated - I done a factory reset and still the same problem - the printer is on my wifi network and there is no firewall

It says Refused. More details at prusa.io:13401

Make sure your printer is connected to WiFi.

pour ma part, j'ai obtenu ce message juste après m'être connecté en WIFI par NFC.
