New XL and connecting to Prusa Connect
The online instructions do not match the form at connect.prusa3d.com. When I go to add the printer there is a code field, I don't know what to enter in that field.
On the printer when I go to add a printer to Prusa Connect, I get an error stating that there is an error "Registration failed. Likely a network error. Tray again later." I do have network, I have tried wireless and ethernet (unless there is a port issue but I don't see anywhere that says I need to open a port). I am connected to Prusalink so I know I have an internet connection.

Following up on the chat on Tuesday, our devs managed to find the issue and solution as well. The problem is that the printed probably had older firmware originally, and with the newer version it did not change the server info about Connect. It does not know what server and port it should connect to. One solution is to do a factory reset on the latest firmware, which will write the correct information to the printer settings. Another, more manual solution, to avoid the factory reset, is to create a file prusa_printer_settings.ini insert the following code in it, and then load it to the printer in menu settings -> system -> load settings from file. [service::connect]hostname = buddy-a.connect.prusa3d.comtls = Trueport = 443
RE: New XL and connecting to Prusa Connect
I am getting the same error, "Registration failed. Likely a network error. Try again later." running the v4.7.0 firmware.
RE: New XL and connecting to Prusa Connect
Have you tried the API key that you should be able to find in the printers menu?
Printer: Original Prusa Mini+
Nozzles: E3D 0.25, E3D Nozzle X 0.4 , E3D 0.4, Bondtech 0.6 CHL
Printables: Tysonsw
Mastodon: [email protected]
.
RE: New XL and connecting to Prusa Connect
Having same issue, there doesn't appear to be an API key in the prusaconnect menu
RE: New XL and connecting to Prusa Connect
Ran out of edit time. The livechat team went through ruling out connection issues- I tried wifi, ethernet and hotspot, all with the same issues.
Homza, the staff member I spoke with on the second occasion was able to connect their demo XL instantly. I still am not able to. Running 4.7.0 firmware.
RE: New XL and connecting to Prusa Connect
I reverted the firmware to 4.6.1 and was able to get the registration code immediately. I then upgraded back to 4.7.0 and it failed as before. I made no changes to my DHCP server or router. On the surface, this appears to be a regression in 4.7.0. I was planning on filing a bug in the Github project today.
RE: New XL and connecting to Prusa Connect
I'm running 4.7 on my XL with no issues, so it must be some combination of fw version and something else.
RE: New XL and connecting to Prusa Connect
That's an interesting observation.
I broke out Wireshark tonight and used port mirroring on my core switch to observe traffic from the XL. While I was able to capture the DHCP handshaking, an NTP time sync operation, and a number of packets when I browse the local Prusa Link page, I do not see any packets when I choose the "Add Printer to Connect" menu item. I was surprised by this, as I expected to at least see some packets transmitted.
This seems to suggest the "something else" is not network related, but related to differences that can very across XLs. One thing I noticed comparing the 4.6.1 and 4.7.0 firmware is that the Prusa Connect code was significantly modified, and in particularly, the APIs they use to fetch EEPROM data to initialize the Prusa Connect driver looks like it is new.
RE: New XL and connecting to Prusa Connect
Does anyone know if I need to do any port forwarding on my router? I'm wondering if that is the case.
RE: New XL and connecting to Prusa Connect
I didn't have to do any.
RE: New XL and connecting to Prusa Connect
I was on chat with Prusa for another issue earlier, and I asked... their response was: Yes, you need to open ports on your router. But then they closed the chat.

RE: New XL and connecting to Prusa Connect
I can confirm that using the prusa_printer_settings.ini method works. I have now successfully added my XL to Connect!
RE: New XL and connecting to Prusa Connect
Can confirm the factory reset has allowed me to register as expected. Did not try the dummy code.
RE: New XL and connecting to Prusa Connect
I got it working with the updated settings added to the USB stick.
For clarity:
[service::connect]
hostname=buddy-a.connect.prusa3d.com
tls=True
port=443
RE:
I needed the "hand made" prusa_printer_settings.ini as well for my XL, i updated it to 4.7.0 before (was sent to me with 4.6.1 on it and the first thing i did was updating the firmware).
RE: New XL and connecting to Prusa Connect
This worked for me. Thanks!!
RE: New XL and connecting to Prusa Connect
I just found this thread since I was getting an error. I'm at 4.7.2 and the above doesn't work for me :-/ Is anyone else on 4.7.2 having issues? Interestingly enough, it initially worked when I got the printer a week ago, but then always showed offline, and now I can't add it back.
RE: New XL and connecting to Prusa Connect
Hi, does it not work even with no print files on the flash drive? What does the connect setting page say in the status?
RE: New XL and connecting to Prusa Connect
I'll try it with no print files, I didn't think that would matter. I'm using the original USB stick that came with it, and it has the wifi credentials in there too. The error is the same as others have gotten "Registration failed. Likely a network error. Try again later."
