Issues solving a bending analysis on threads in pin-box connection

Hello Everyone,

I am trying to do a study on my threaded pin-box connection related to bending, where I want to see the effect of bending on my engaged threads. I build up intentional interference of 0.010" at the shoulder to study the effect of makeup torque and it ran fine but while trying to run bending moment on the outside face of box through a connector at centre point, Solution does not converge beyond 20% of my load & diverges at 20%. Attachment carries my load case and setup screenshots. Can you please help me understand what am I doing wrong or any additional way to make it work.  @John_Holtz
