Unable to dock with certain gates

[tyrannishawk]

No NPC's nearby (rarely see them in Gallia by the way). Also not a docking queue. I am all alone at the gate.
My (Freelancer) ID is active and no cargo or cargo in my hold also doesn't seem to be a factor.

I'm running the same trade run over and over again to save cash for a new ship. Now, the Provence -> Ile-de-France gate will let me jump. I have the same ship, configuration and cargo as the previous run (where I had to use the jump hole because the gate wouldn't let me dock) and now I am able to dock with the gate.
