I looked around and can only see where I cannot leave my current solar system to go to another galaxy. BTW didn't we do it in the old game? I see lots of other systems, but not connections to get there. Anything would be appreciated...
The connections are only a record of where you have traveled, not what’s possible. In vanilla, you can warp up to 30 LY. So if a system is within 30 LY, lock it and warp to it.
Also in Vanilla only CV can warp from solar system to solar system. SV are restricted to in-system-warps (between belts, planets, etc).
