An issue with the connector in the Stress Analysis

I'm trying to model pressured round membrane in Solid Mechanics. The situation is shown in the attached diagram. The task is to define maximum stress, which appears near the membrane-to-fixed attachment. Pressured surface I described as Boundary Load -> Pressure. And I got analytical formulae to calculate maximum stress, but model results differ.
The thing is I'm not sure how to model boundary conditions. I tried Fixed Constraint surfaces on the edge of the membrane or adding Rigid Domain binding rings (as in the picture), not sure about Roller Connector. As I can see, the finer mesh I make the higher stress values I got near attachment.
So any advice how to make realistic boundary conditions would be helpful.
I made 3D geometry due to my membrane is quite thick.
Thanks
