mini5+ cannot load webUI on macOS 12.0.1

[Mentaluproar]

In both safari and Firefox, I cannot load the webUI completely. The farthest it gets is in safari, where I gets some UI elements and dark mode down after a while, but goes no further, showing a failed to connect network error in the lower right corner. When I try to access it off my iPhone mini, though, it pops up fast and error free. I cannot figure out what's wrong.

Have you tried chrome?

What DWC version is installed on the Duet?

Do you have any browser plugins that may be blocking something?

@mentaluproar what's your AV/Firewall?

[Mentaluproar]

@pkos no AV, just the built in firewall on macOS.
@Phaedrux 3.3.0. I Don't use chrome. I avoid Google products when I can.

EDIT: I forgot I have lockdown installed! Turning it off fixed this. But what is lockdown blocking that breaks DWC?

@mentaluproar If I read correctly, lockdown is a form of a firewall and privacy tool.
So one could compare it against eset - which is what I have and I have exactly the same issues as you do. I have to disable web protection in my eset to be able to use the DWC. This came on with a DWC change a while back.
