Loose boden tube

[Brucy19]

I've had great prints right out of the starting gate with my Ender 3 Pro. Some of which took 18 hours or more turned out great. I went today to print a part and came down 3 hours later to find the boden tube detached. I stopped the print, reinserted the tube and started the print over again. 30 mins later I checked again to find same boden tube again detached. Please notice it's not the white boden tube problem, but rather a brass fitting now keeps popping out of the filament drive. How do I rectify this? Press in harder? Small dab of epoxy glue?
It may be a $200 printer but for my very first 3D printer, I've had no issues until this.
