D6000 Dell Dock isn't recognizing DP port

[fvilelabr]

I have 2 monitors connected on my D6000. Out of blue the monitor connected by DP port stopped work. it's working only the monitor connected by HDMI.

It's a Macbook Pro and i've updated Mac to Monterrey 12.0.1

Does anyone can help me?

Try unplug and back
Check if the DP cables fit well in all the sockets (I lost 20 min because of that)
Im on Monterey 12.0.1 also

I've tried it a lot of time. Doesn't work.
It was working fine, all of a sudden it happened.
From now, only HDMI port is working =/
