bug Communication Error Before Injection (Blank Browser Screen)

[Issus]

Hey I'm having trouble with a weird bug that's preventing me from injecting into my game through the QR code reader:

>I put in the pokemon I want in pkhex

>Click "QR"

>Read QR code with the reader

>It takes me to the browser like it should

>Instead of the screen going black and saying Injecting, it just has a generic communication error with a blank white screen that does nothing

I'm using an un-updated 3ds for this and have been for months now, and this is the first time I've encountered this bug.
