Cannot connect to Bambulab Cloud from Italy

Other topics
1

Hi,

it’s 3-4 days people in Italy cannot connect to cloud. This is limited to TIM internet provider and some other local minor providers. We needed to move to LAN mode.

I suspect DNS or NAT issues, but I cannot be sure.

Any help is appreciated.

Thanks.

Do you actively have connection to WIfi or internet? Or just LAN?

My p1s Is connected to the internet via WiFi and internet connection isn’t lost during the issue. Download starts and get stuck at 0%. Issue is reported by all customers of the same ISP.

If it is a DNS issue, it is not Bambu’s problem. Complain to your internet provider.

While you are waiting for them to find the error, change the DNS server for your computer or router, or add secondary DNS addresses to be searched when the primary server fails.

Here are specific DNS provider addresses in Italy based on search results:

  • Smart DNS (Milan): 95.141.39.236
  • Vodafone Italia S.p.A.: 93.64.222.78
  • Brennercom S.p.A. (Soraga):
  • Connesi S.p.a. (Recanati):
  • Fastwebnet: 93.45.244.86

Globally Available (Popular in Italy):

  • Cloudflare: 1.1.1.1
  • Google: 8.8.8.8
  • OpenDNS: 208.67.222.222
  • Quad9: 9.9.9.9

Some will be faster than others, depending on your location.

Their domestic router cannot be configured with different DNS so I cannot try and verify it’s DNS. Issue isn’t limited to 1 single ISP but it’s mostly reported by TIM customers.

Also I would argue Bambulab business is impacted by ISP and that is money loss for them.

Actually, this would be a good time (and reason) for you to consider going LAN mode only and drop Bambu cloud.

A router from the ISP can limit your options, but the computer’s DNS settings can be changed to use addresses from servers other than the router or the ISP.

A search for “Windows how to add DNS server” (or your operating system) should provide instructions.

Sure you can do that, but you need to configure DNS to the printer as well…

I’m actually trying again, I made an attempt time ago already. I now have home assistant with integration and I this is a replacement for Bambu handy. Bambu Studio bugs apart that can be solved by OrcaSlicer, I agree time is good enough for switching to LAN mode.

I have TIM and i have setted different DNS servers on my modem, and nothing changed.
For some reasons i can’t use LAN mode. The printer is detected, but it won’t connect -_-

Same problem here, download starts then stops indefinitely.

It’s been some weeks I have lots of problem with the service, Bambulab never reports incidents but we customer can’t print.

This is the only service having problems in my house, everything else is fully operational.

Edit: printer is connected, I can see status, the stream is running ok, I can see AMS filament.

I suspect this is more related to NAT on ISP side. BTW to enable LAN mode I suspect you need the Cloud, this is genius! I managed to do the switch by doing hotspot with mobile phone that has different ISP.

13

How is that “genius “, when to switch to LAN mode you have to go through Bambu’s cloud? I’d say it’s quite the opposite.

14

You do NOT need the cloud to enable LAN mode.

  • Enable LAN mode on the printer display.
  • If the printer has recent firmware, also use the display to also enable Developer mode, removing the Bambu “authorization” requirement.
  • Provide the printer IP address, LAN access code, and serial number on the Device tab of Studio.
  • Print.

I agree with you with the procedure but for whatever reason I couldn’t establish connection to the printer over the LAN. I had to go through the Cloud with an hotspot and different ISP and then redo the LAN+Dev mode switch. Perhaps it’s been just coincidence but if people is having troubles doing the switch, maybe hotspot is worth a try.

I have absolutely no issue at all with any other service with TIM.

I did open a ticket to Bambulab and they said (lol) they have no other tickets about tim and that i should check my wifi. Great.

I was about to buy another Bambulab printer, but maybe this should mke me change my mind.

17

My guess, educated but not supported by any evidence, is that TIM’s NAT is now preventing Cloud to contact the printers. I imagine they use STUN server and similar solutions but maybe TIM is now blocking that as well.

18

Maybe you should put it on hold….for the time being.

Thomas tell me how to open the ticket so that they’ll have 2

Why is it Bambu’s issue when a ISP blocks or changes things that limit the connection in the middle?

I’m just asking to understand.
