@Lamooth Is it just on the Mac?
I remember having this problem for a long time - including duet resets midprint because of this. But this was in and before 3.2. Now it still happens every now and then, but never resets the Duet. At worst, I can't load the GUI at all, at best - I get a gray overlay over the GUI which prevents me from clicking stuff on the GUI, but at least I can see what's going on (this is much more often and worse when using BambuStudio-SoftFever edition).
The errors, freezes and resets only happened on Mac (regardless of browser) - never on Windows.
The one thing that could help was disabling Eset's Firewall I had installed.
