Recently, I got a flat tire (rear). While changing out the tire, I unplugged the circular pin plug/jack thing where the wire attaches near the rear hub motor. Afterward, when I replugged it, I keep getting an error message. I tried turning the plug again and again to try all the different lineups but I just keep getting the error message. 

Can someone tell me the right way it's supposed to go, and if there is some kind of reset I need to do.

This is all for a Fold X.

And thank you.

If it's anything like my non-fold XS, while the connector isn't exactly keyed, the pins within it are offset a bit so it will only connect one way.  I'm thinking you just haven't got it fully seated in the correct orientation.

You can see in the attached picture, the terminals aren't equally spaced from the center, they're offset a bit so it'll only connect one way.

Wow, that’s a wacky connector.   I wonder why there’s so many pins.  Most of my brushless motor experience comes from Radio Control cars and drones   They’ve all had just the three wires going to the motor(s).  My Sondors is the same way.  Yours is just.....weird.

Anyway, it appears it can only connect one way.  I’m basing that on the larger pins at the top, left, and right side of the connector in your picture. 

Does the female end have three matching large sockets for these pins?

You said you turned the connector to try all 8 possible combinations, but it appears that’s not possible. This can only plug in one way.

Perhaps mark the center large pin (the one at 1 o’clock in your picture) on the outside of the male connector with a paint marker.  Do the same for the female end.  This way, you’ll at least know your cable is aligned properly.  Once done, line them up and jam them together.  The connectors should join a bit tighter in the correct orientation.  I’m guessing by 1/4 to 3/8 of an inch.

Your Connector is not Weird or Wacky, the FoldX just has a different plug than the Sondors Fats and it, as all Sondors motor to controller connector, have 9 pins. The three larger are power and the 6 smaller are Hall Sensor and that’s probably a Hall Sensor Failure Error Code you are seeing reported. 
I see what might be 2 problems in your photograph. 
First it looks like you have the rear wheel axel installed backwards in your photo. The Slot in the axel should face forward towards the front of the bike. That allows necessary cable length for connecting to the other connector going to the controller, and that might limit the two connectors from complete connection. If this is so, remove your rear wheel and turn your motor axel 180° in  the dropouts to align it properly. Then see if your motor cable will seat completely in the two connector halves.

The second potential problem I see is where the spiral wound wire on the cable as it exits the motor axel is meant to reside in the slot and protect the insulation on the motor cable from damage due to the sharp edges of the motor axel cable slot. It’s as if your motor cable has been pulled out of the axel. That could dislodge any of the 9 individual wires inside the motor and that could be your problem. If that is the case, only a new motor replaced in your existing wheel will remedy the problem because most eBikes shops are not likely to disassemble your motor to repair the wiring.
