Rekordbox link button not showing (XDJ-RX2)

So I got this problem where my LINK button will stop coming up randomly.

Normally I fix it with reinstalling rekordbox and the drivers but today that didn't do the trick.

It seems that my rekordbox randomly decides to stop showing the LINK button.
This happend to me a few time before and I usally reinstall rekordbox and the drivers for my XDJ-RX2.
But today that didn't do the trick. It's very annoying that I have to do this every f***** time this problems pops up.
I was thinking maybe because of an update but that isn't the case since the last time I updated everything all worked fine.

Things I tried:
* Disabling my firewall
* Changed the network type to private (which it was already on)
* Disabled file sharing
* Checked my connections (I only have a ethernet cable connection, no wifi)
* Scanned for malware and viruses (I let it autoscan everyday didn't find anything in the last week)
* Checked for third party programs that could potentially block connections (didn't had any)

I have my XDJ-RX2 directly connected to my computer worked fine last week. I saw some posts about connecting it with an ethernet cable however it doesn't seem that my XDJ-RX2 has a port for that.
I didn't change anything remotely to rekordbox or the drivers (or anything else close to that for that matter)

Anybody have any idea how to fix this randomly recurring problem?
