D4 not working with 300 2.8 D (older version) but works with 2x teleconverter

I purchased a used D4 and it works perfectly with my lenses EXCEPT for my older 300 2.8 AF-S D. Funny thing is, I connect a 2x teleconverter between the camera and lens and it works fine. The 300 2.8 works great on my other Nikon camera. I did a light wipe of the contacts and it did not help.

Could it be as simple as needing a "strong" wipe using alcohol or other cleaner on the contacts? Nikon Tech support wants me to send in both pieces (meaning I'll be without both for 2-3 weeks + unknown repair costs)

Sorry if this is in wrong posting area. Any feedback would be really, really appreciated.

If it works fine when using a teleconverter then there can't be anything wrong with the contacts as it still wouldn't work with the teleconverter. Perhaps there's an issue with the compatibility of the 300mm with the D4 that the teleconverter resolves?
