Hi All,
I have been struggling to resolve this problem for long time as well!!
But I am able to fix it by following a method that I saw online. I unplug everything from my laptop and leave it alone. Then long press the power button for 40 seconds, have to be exactly 40 seconds! Then turn on the laptop and connect all cable, HDMI/USBC wire.
It works well now! I am about to connect two monitors at the same time !

Hi, I tried hard reset - hold power button on your PC till turn off. This simple solution worked.
Hardware:
Dock: HP USB-C G5
Laptop: HP Zbook Fury G8 15" running Windows 10
Monitor 1: Dell P2715Q 4K connected to dock via DisplayPort
Monitor 2: Dell U2415b FHD 1920x1200, connected to dock via HDMI
Ethernet from my router also runs into the dock
For about the last year, this setup has worked flawlessly. Connecting via USB-C, both monitors worked perfectly, both with the laptop open (i.e. 3 screens total) and with it closed. Laptop charged over USB-C just fine. Internet/LAN workd over USB-C as well. Everything was peachy.
Today I noticed that the 4k monitor was connected to the dock via HDMI and the FHD monitor via DisplayPort. For some reason, I decided to switch them around. I disconnected the laptop from the dock, switched the DisplayPort and HDMI cables between monitors, and reconnected everything. At this point, the monitors stopped being recognized by the dock.
when laptop is connected to the dock, the Ethernet and power/charging from the dock work fine. USB-A and USB-C ports on the dock are also working. But monitors hooked up to the dock are not detected on the laptop.
when disconnecting/reconnecting to the dock, the monitor will briefly light up like it is about to do something, then goes back to black with the message "entering power saving mode". Both monitors do the same thing, both via HDMI and via DisplayPort
when either monitor is connected directly to the laptop via the laptop's HDMI port, both work fine. Windows auto-detects the monitor at the correct resolution, I am able to use it as a 2nd screen.
other USB-C devices work fine when connected directly to the laptop e.g. USB-C hard drives
the dock does show up in Device Manager under "USB devices"
I have gone down the rabbit hole Googling, and have found people with perhaps similar issues, but trying their recommended solutions has not worked for me. Here is what I have tried so far:
switching monitors back to original configuration (4K on HDMI, FHD on DisplayPort), no longer works. Both monitors are not detected.
restarting laptop, no change
"hard reset" laptop by disconnecting dock, powering off, holding power button for ~30 seconds, and letting it boot up again. Didn't fix it.
removing/reinstalling laptop battery, no change
power cycling dock (disconnect power for ~60 seconds reconnect), no change
updated dock firmware, it was already on latest firmware but force-reinstalled firmware anyway, no change
updated laptop Thunderbolt driver, no change
updated integrated Intel graphics driver, no change
updated NVIDIA dedicated GPU graphics driver, no change
updated "Integrated Intel Chipset" driver from HP website, no change
At this point, I am out of ideas, and kicking myself for messing with a setup that working perfectly in the first place. Any help or input would be much appreciated.
UPDATE: The problem seems to be the dock. Swapping out the dock for another of the same model works fine. Will probably need to replace the dock.
