The Digital Optical port on the back which is lighted is no longer. So it's not the panacea I had hoped as I can see some things correctly but not others of significance.ĬalDigit docking station after all the troubleshooting just died. But in the middle of everything it did see the docking station.

Sadly I just checked the Mac System Report and Thunderbolt still reports no devices connected to its bus ports.
The display and cable were working, it was the Mac that got into a state where it could not see external Thunderbolt devices. Given all my troubleshooting I believe the culprit was the Mac itself. At this point I was in the simplest configuration: display connected directly to laptop and no docking station. I finally tried powering off the power strip and powering everything back on at once. The aggregate of the successful answers here suggested this was a power sequencing issue. In my case all the troubleshooting loosened the plug into the docking station transformer. Similarly the monitor has a cord with two ends, make sure both are snug.
The docking station has a transformer which plugs into the power strip and then the transformer plugs into the docking station.
Power cables: I know this sounds stupid, but check each point in the power chain. The hardware I had been using for the last couple of weeks successfully (display, docking station) had no changes. 
Recent history: Nothing changed on my computer (at least that I initiated). Googled to find the magical hidden Apple button to detect external displays (System Preferences -> Displays -> hold down Option button to cause magical button Detect Displays to appear), nothing detected. Power cycled display on boot it reported no DP device detected. Detection: Try having each side detect the other. Power cycle display while connected to computer (didn't work). Reboot computer with display connected (didn't work). Connection sequences: Tried rebooting computer with display disconnected, connect display to computer directly (didn't work). Before I eliminated the docking station I was able to see the CalDigit connected and supplying power, but no display connected even though the display was connected to the CalDigit. lets you see the Mac's view of what is connected. Diagnostics: Apple -> About this Mac -> System Report. #Thunderbolt dock for mac book pro 2018 drivers
Drivers/OS updates: It was a working and stable configuration for some time, with no intervening updates before it stopped working, so don't destabilize the environment by changing drivers before troubleshooting. So plug in your computer using its power supply. In other words computer may disable hi res displays on battery power. Confirm power: I have seen references that higher resolution displays cannot be supported without direct power for your computer. Confirm computer: reboot computer, try plugging, unplugging display into computer (didn't work). disconnected docking station, connected display directly to computer (didn't work) Simplify: eliminate everything in the chain possible, get it working then add back. 
Confirm display cable: didn't have another USB C computer to connect to (skipped). Confirm display: connect to another computer (worked). The basic troubleshooting strategies applied were: I spent HOURS today trying every combination of troubleshooting under the sun. #Thunderbolt dock for mac book pro 2018 plus
CalDigit TS3 Plus with Thunderbolt 3 cable. No display -after weeks of this sequence followed successfully, and new gear (one month old display, cable, docking station). The only crime I did was to unplug the Mac from the dock and plug it back into the dock later. The same malaise hit my external monitor today.
