Description

When testing #13260 I noticed that examples/dtls-wolfssl is not working on pba-d-01-kw2x.
I didn't have time to investigate yet so this is just to keep track of the problem.

Steps to reproduce the issue

On one board:

BOARD=pba-d-01-kw2x make -C examples/dtls-wolfssl all flash term
ifconfig
*copy the IP*
dtlss

On another board:

BOARD=pba-d-01-kw2x make -C examples/dtls-wolfssl all flash term
dtlsc <IP of the other node>

Expected results

The example works.

Actual results

Connection times out on the client.
