Need Help with my Network setup and Fluidd | 3D Printing | Page 1

I use a Creality wifi Box running KlipperWrt with Klipper (instead of a pi). Yesterday suddently I wasn't able to connect to the web interface Fluidd through my PC anymore. It works from my phone and notebook however, which are connected to the wifi. The PC is connected via ethernet and the Creality box via wifi. You can see the network topology in the picture.

Does anyone know what could be the cause here?

It's possible that there may be an issue with the network configuration on your PC. Here are a few troubleshooting steps you can try:

Ensure that your PC is connected to the same Wi-Fi network as the Creality Box. Check the network settings on your PC to confirm this.
Restart your PC and the Creality Box. Sometimes a simple restart can resolve connectivity issues.
Disable any firewall or antivirus software on your PC temporarily and see if that allows you to connect to the web interface. If so, you may need to adjust the settings of your security software to allow the connection.
Try accessing the web interface using a different web browser on your PC. Sometimes browser extensions or settings can interfere with accessing certain web interfaces.
Double-check that the IP address of your Creality Box hasn't changed. If it has, you may need to update the IP address in your PC's network settings or in the web interface URL.
If possible, temporarily connect your PC...

how are you accessing the printer from your PC?

normal oar Jun 30, 2023, 6:32 PM

#

Through the IP address of the box

rotund steppe Jun 30, 2023, 6:33 PM

#

Not DNS then - what error do you get when you attempt to access it?

#

@rotund steppe not a hard reset on the box itself. That would delete everything. The weird thing is that it stopped working out of nowhere, so it must have to do something with the network and router settings

rotund steppe Jun 30, 2023, 6:53 PM

#

Yes, the fact your hostname doesnt resolve is odd

#

I wouldnt hard reset but a restart might resolve that

normal oar Jun 30, 2023, 6:54 PM

#

I mean it was powered on and off a few times now since yesterday

night surge Jun 30, 2023, 7:10 PM

#

You're on different network segment

normal oar Jun 30, 2023, 7:11 PM

#

But it has worked until now like this

#

so the wifi router must have changed somethign on its own

#

What should I look for in the settings? there's a lot I have no idea about

night surge Jun 30, 2023, 7:13 PM

#

I don't know what happen but different network segment will not communicate unless there's routing for it.

normal oar Jun 30, 2023, 7:14 PM

#

so can I setup up a route between them?

night surge Jun 30, 2023, 7:14 PM

#

The simplest way is to make all your devices on one segment.

normal oar Jun 30, 2023, 7:15 PM

#

but I have no wifi on my PC

#

and it's connected using ethernet directly to the main wifi router. the printer is in a room where I have no ethernet cable and no wifi signal of the main router

night surge Jun 30, 2023, 7:17 PM

#

Then you need to setup routing on your routers.

normal oar Jun 30, 2023, 7:18 PM

#

#

this?

night surge Jun 30, 2023, 7:19 PM

#

I don't understand your language...

normal oar Jun 30, 2023, 7:20 PM

#

sry I'll do some research myself on the specific router. I'll come back if I can't figure it out

#

thanks for the help

night surge Jun 30, 2023, 7:28 PM

#

One more thing, sometimes it's easier and faster to just factory reset you routers and set everything from scratch. Home routers usually have setup wizard that automatically set everything.

normal oar Jun 30, 2023, 7:32 PM

#

yeah I haven't changed anything in the settings, so I should be able to do that. Just seems weird to me that it was working fine for a year and now suddenly something must have changed but I don't see anything different or new in the settings

normal oar Jun 30, 2023, 7:55 PM

#

Shouldn't they both be in the same network and subnet as they both have a 192.168.1.x IP? A different subnet would be 192.168.2.x or have I misunderstood this??

night surge Jul 2, 2023, 8:59 AM

Where the picture come from? Is it from your router?

#

Assuming it's from your router and you only have one router, the only thing I can think of is there's firewall preventing the access.

Has this change? In the picture it's 192.168.3.1

normal oar Jul 2, 2023, 9:19 AM

#

That's just how I can access the KlipperWRT interface. I followed a tutorial about this. But accessing the Fluidd interface and boxes IP is 192.168.1.xxx

night surge Jul 2, 2023, 9:20 AM

#

And you access it from your pc?

normal oar Jul 2, 2023, 9:22 AM

#

No that's for when I'm connected directly to the Creality Boxes wifi with my phone or laptop

#

And this hasn't been changed. I've checked the settings and it's all the same as when I installed it

night surge Jul 2, 2023, 9:24 AM

#

I'm sorry but I don't use klipper nor creality boxes, so I don't know how it works. But from networking perspective it means you have 2 different network, is that correct?

normal oar Jul 2, 2023, 9:30 AM

#

There's the main router to which a Devolo Powerline device is connected, to which the Printer is connected via wifi to

#

But that doesn't mean it's a complete different network, right?

night surge Jul 2, 2023, 9:34 AM

#

Yeah, I don't know how to explain it exactly, but your klipper has it's own network.

#

You might want to double check the printer's network setting. Just to make sure. The thing that's weird to me is that unless your printer have 2 network interface, it should only have 1 ip. It can have multiple ip's but that's complicate things, unless you are familiar with networking, it's not advisable.

normal oar Jul 2, 2023, 9:44 AM

#

I honestly don't know why that is. I followed the only tutorial out there and it didn't fully explain all steps. But that it has been working for over a year until now without touching it is strange. I've tried reaching out to the dev behind this KlipperWRT thing but he's not very active at all and neither is their discord group

Other devices I tried pinging are smartphones or laptops, so there might be some older protocols on the Creality box that aren't safe for the windows firewall
