Camera Stops Working

Creality Flagship Series Creality Flagship K1 Max
1

I am having an issue with my camera going into a “x.x.x.x rejected our connection”

However, I am on the latest firmware and have had this issue for the last 4-5 versions. A reboot clears it but it comes right back.

I’ve submitted it to creality twice, never heard back at all. In the event anyone from creality comes across, I’d be happy to pull logs / wireshark / whatever you need.

I’ve found some other posts on here that the latest firmware resolved it, which is great, but has not for me.

It’s not a hardware issue that I can tell, as it consistantly comes back post reboot, then stops working after 10-30 minutes.

No retransmits or network drops on my side, it is pretty clearly a bug.

Hello @gorgarp and Welcome to the Creality Forum…! :wave:Creality

Sorry no one has been able to figure out this issue…
Have you tried to connect with the Ethernet port instead of wireless just to check it out…? I think the K1 and K1 Max both have ethernet ports…

Hello. I just tested it. No luck.

It is also worth nothing, I ran wireshark and am not seeing any dropped packets or retransmits. (You can see in the image above)

If there is any documentation on the handshake being used to connect to the camera, I can likely capture that to ensure it’s occurring correctly.

Does anyone know how to get a bug report in front of them? I’ve tried submitting via two methods but haven’t heard anything back (months ago on one, the other about a week)

TBH one would think a code defect on their “flagship” would be a bit higher priority, especially on the primary “value differentiator” between the K1 & K1 Max but yeah, not so much.

I’m also having this issue with the camera not responding after I start a print. I just upgraded firmware a few days ago, and that’s when the issue started. I even had the printer crash and reboot in the middle of a print today. Printer is only a couple of weeks old, and it’s been solid until the firmware update. The camera issue occurs on both the desktop and mobile app. I’m directly connected to ethernet on my network. Only way to restore the camera is to reboot the printer.

That is the exact same behavior I’m seeing.

I have confirmed it is pretty much a firmware issue. I’ve rooted, installed mainsail, and used orca slicer to do a print, the camera freezes.

As I thought:

Usb keeps connecting and disconnecting until it can’t connect anymore (likely a kernel safeguard)
