Could not teleport. Failed to grant capabilities

I'm using the Kirsten Viewer 1.16.3 (90), and I'm getting this message when attempting to teleport to my home sim.

A friend of mine who has also logged out there was routed, rather embarassingly, to a 'nearby location' (read: Linden hub).

Could someone please inform me as to what this message means? Thank you.


Edit: This is no longer necessary. Turned out the sim was down for awhile. That's all.

This was an impact of the rolling restarts. We will probably see it a lot tomorrow as well, when they do the other half of the grid.
