WHich Forum is Which and how can I combine them?

I posted a question in the networking forum here: A NordVPN update caused NordVpn to stop working on the Command line — Linux Foundation Forums.

When I created an account I did so from the other website. When I went back to check on it I could not navigate to it from LFX. I actually had to re-search for it again. And yet this website (which I have never seen before) knows who I am and authenticated me, but I appear to have a different name here.

What is the difference between these forums? Whats going on? Can I re-ask the question on this forum (since I received no replies in the other). Or am I in the twilight zone?
