Yep resistance for bosses will do that to you especially in a game such as FGO since even normal enemies will resist the stun if it is chance based.

In this case, you facing a boss who resist it, but did you got any debuffs on the enemies?

IIRC if you use one of those upgraded master skills for this event, they will do additional effects when they have been upgraded/replaced with another master skills.

Also if this attempt fails, you might been forced to use those command spells at that point.
