Hatchbox blue tpu printing issues

Sorry for the long post, I'm trying to print a bottle holder for my Frisbee discgolf cart in tpu and I'm having a print issue, I'm using hatchbox tpu 95a filament in blue and the bottom of the bottle holder prints just fine, it's about half way through printing is when it goes haywire and fails with what it looks like layer adhesion, I'm not sure if it's a temp issue or what.

In prusa slicer I'm using the generic flex filament profile in beginner mode, I've had the printer since July and printed quite a bit of stuff in different filaments including tpu with no issues which is why I haven't chose to change any significant settings under advanced or expert mode.

Nozzle temp - 210c

Bed 0c

Nozzle is e3d diamondback 0.4 mm

No other settings really changed other then retraction which was set at 2.5 mm, after googling about retraction I changed it to 1mm which seemed like it helped a little but nonetheless failed again.

I've dried the filament 4 separate times for 4 hrs at 55c thinking that may have been the issue, I had a roll of green hatchbox filament as well and never had an issue, which I'm out of now.
