New WH Brake Master Cylinder Leak

[DeezNCSU]

Next on my list of problems is a leak on my Wild horses brake master cylinder, kit is K7045, which is essentially brand new. The paint is also new but this drip has caused it to bubble. Fluid leaks from the plug circled in the attached pic and no matter how much I tighten it or mess with it, there is no change. Fluid only drains out when I drive it, not when it sits. Planning to call WH on Monday, but is there some obvious and easy fix?

Have you checked the threads on either the plug that’s circled and/or the inner threads to see if there’s a piece of grit in the threads or a bad thread that’s causing the leak? Maybe not but can’t hurt to check.

I haven’t yet, didn’t want to drink and have to bleed them until I had some ideas.
