Print Plate blocked by VPN?

I ran into an issue the past day or two where when sending a plate through the cloud service it will fail to send fully. The file will send but errors and will not start the printer. This is with my VPN on, when I turned the VPN off it sent successfully.

Things to note:

  • Hangs at 97% on “Sending print configuration”
  • Fails at “Sending print job though cloud service”
  • Print Plate will send the 3mf file and file is viewable on SD Card.
  • Can manually tell 3mf file on SD card to print from BambuStudio, and it will.
  • Can view camera and printer status.
  • While using the same VPN service on my phone the Bambu Handy app works and can send a file that prints.
  • Bambu services are all operation (link provided by error reason)

Thoughts and suggestions?

If you are with Nord, then that’s your problem.
They don’t offer any port forwarding or tunnelling, great for most things, not that good for P2P and useless for our printers.
For me it is only usable in LAN only mode and with all local network traffic being excluded from the VPN.
As soon as I run the VPN in normal mode or try the cloud mode for the printer all sorts of problems start, including weird print issues like yours.

I isolated two possible reasons.

  1. Many servers refuse to work with VPN’s unless you also have a fixed IP.
  2. Depending on how you do it there is also a fair chance a server will just block you for security reasons, like when your IP keeps changing with every connect and sometimes comes from strange countries.

I had huge problems getting into our companies systems from home, you know, all apps and such server based…
Thought my security standards and measures were just to high but turns out Cloudflare does not really like people using VPN’s.
So I have to set exclusions for the vital ip ranges our system use so I could access them without going through Nord :frowning:
