Difficulty to converge non linear analysis with sliding contact

Hi all!
I'm trying to run a customer application that consist to run a non-linear static analysis in a cylinder clip.

Please, take a look attached video with analysis setup detail.

Contact stiffness was changed to 0,005 due to dissimilar material applied, as described in topic " Dissimilar material stiffness in contact" in post below:

It was having some contact penetration and it is solved after change contact parameter Max Allowable Penetration to 0,01.

Contact Max Activation Distance is defined 25mm to create contact elements enough to relative parts motion.

At around 46% of first step, the analysis is resulting bisecting error:

It appears that Nastran has some difficulty converging sliding contact in this model.
Are there any parameters that should be changed to improve the sliding contact?
Are there any parameters that were set incorrectly?
Thanks in advance to help me with this case.

Regards
