Гениально. Спасибо огромное!!!
I have tried all the solutions I read above. but nothing worked. At least ı have a certain solution. Download Bambu Connect from bambulabs official website. Create your project on bambu studio after slicing your plate export your project as sliced plate. finally send it to your printer by using bambu connect .
Me ha funcionado, Gracias!!
Spot on Smejky, it worked for me, thank you
Being old and lazy …
I finally decided to click the “Cancel” button which then changed to “Send” …
after about 7 x tries, the file was finally transmitted!t
Thus, I finally discovered patience + persistence really pays off!
I hope this is of assistance to others.
(Being an ancient analyst, I assume that Bambu Lab’s Cloud servers sometimes/often (?) get hammered too hard!)
(Too many people, expecting too much of Windows 11 and Microsoft - luckily I don’t suffer from those delusions and still use Win7 machines for my development work!)
Vielen, vielen Dank. Ich wusste mir kein Rat mehr, und was man dann meistens an Ratschläge bekommt, macht es auch nicht besser. Ich verstehe nicht warum der Fehler nicht behoben wir.
Works for me, thank you very much
Genius! Very very helpful!
I did not print anything for over an year because I had problems with my healt. But now I am better and wanted to print again a small sample first.
I had the same problem. I first downloaded and installed a root certifacte from amzon (because I found this to be a solution on some other side first) and then tried the two commands above. The first succeded, by the second thew an error:
Connecting the app on the phone said that I should scan the QR-Code on the printer. There was no QR-Code. Perhaps because it is printing. But verifying with bluetooth worked.
Any ideas how to fix the certificate?
Thanks much
This worked for me. Thank you.
Cheguei nesse link pesquisando o erro -3030 e depois de ler muitas e muitas mensagens e principalmente o uso do comando para atualizar os SSL do Windows, que não deram certo aqui, lendo a documentação “Suporte para atualizações de raiz confiáveis urgentes para Windows Root Certificate Program no Windows“ da Microsoft descontinuou o comando a algum tempo e aqui pelo menos não deu certo, depois de muitas tentativas rodei o Windows Update na mão mesmo com a indicação de que o Windows estava atualizado e isso resolveu meu problema. O pacote instalou a “Atualização para Windows Security platform - KB5007651” e depois disso consegui voltar a imprimir à partir do Bambulab Studio. Nota, testei via celular e funcionou todo o tempo e portanto é um problema estritamente ligado ao Windows e suas atualizações de SSL. Nota 2: Eu uso PJeOffice e fiquei receoso de conflitos mas não ocorreram, não há conflito sobre isso.

I arrived at this link while researching error -3030. After reading many messages, especially suggestions to use the command to update Windows SSL certificates, which did not work here, I checked the documentation (Support for urgent Trusted Root updates for Windows Root Certificate Program in Windows). It appears Microsoft discontinued that command some time ago, and at least in my case it did not work.
After many attempts, I manually ran Windows Update, even though Windows indicated that the system was already up to date. That resolved my problem. The update installed the package “Update for Windows Security Platform - KB5007651”, and after that I was able to print again from BambuLab Studio.
Note: I tested printing from my phone and it worked the entire time, so this seems to be strictly a Windows issue related to SSL updates.
Note 2: I use PJeOffice and was concerned about possible conflicts, but none occurred. There is no conflict related to that.

This worked to bypass the error for me on the A1 mini!! Try this to bypass folks!! Printing now, finally after 24 hours of this error, no VPN.
Fixed mine right away. Just had to run cmd as an administrator
funciona muchas gracias bro
Gracias eres un maquina. llevaba con el problema 1 mes y nadie me daba solución
March 2026 and you fixed my issue too!
You are my savior, thanks
I’ve been getting the same error message 3030 trying to send prints to my A1 and A1 mini.
From my laptop I can see and control my printers but I’m not able to send prints.
I updated windows, disabled VPN and still nothing
I discovered a workaround by just sending the file to the printers storage and then manually printing from the screen on the printer.
It’s not perfect, but it makes it possible to print with an extra step.
I’m going to keep trying to make it work the way it should.
But I thought I’d post this to give someone an option to print until they solve the issue
I’ll be honest, it was pretty frustrating. I was getting to used to printing from the app.
I’d rather have to option to modify the files before printing
