External monitor turning off with Thunderbolt 3 dock -Lenovo X1 Carbon

I have a Lenovo X1 Carbon 6th gen laptop and just got a CalDigit Thunderbolt 3 dock. I've gotten the USB ports to work but the monitor (Dell u2415h), which is connected with a DisplayPort cable, doesn't work.

When the monitor is first plugged in I can use xrandr to configure the settings properly and it works normally for a few seconds. Then every couple of seconds it goes black, then back to normal. It does this a couple of times and then turns off completely.

This only happens when it's connected through the dock, not when its plugged in directly via DisplayPort / USB-C cable.

Any ideas?

Here's the Xorg log:

Re: External monitor turning off with Thunderbolt 3 dock -Lenovo X1 Carbon

Was there ever a resolution to this? I'm having the same issue, where everything from the dock gets removed every few minutes. The monitor comes back but my USB keyboard doesn't until a reboot.
