Bug Description

Virtual printer does not accept jobs anymore after updating to v0.2.2. Bambu studio hangs a while at 10%, then responds with a connection error offering me to retry or reconnect, both of which fail. I can see the virtual printer in the device tab, I have the all certificates saved in printer.cer, the bbl_ca.crt and the one in virtual_printer/1/

Expected Behavior

When I hit send in bambu studio, I expect the file to upload to bambuddy.

Steps to Reproduce

Go to bambu studio
Slice print file
Hit send
Select the bambuddy virtual printer
Hit send again
Get the error
