I understand however could you then not restore those two posts and edit to remove all the links or all but the first link?
I spent some time putting the text together and the posts were just deleted by so I can not restore and edit them myself.
Yes, that's fair. I've been restored your two posts, and removed most of the links.
We are skeptical about fresh users, who post a lot of links. Just skip the links and post what you have to say.
FLIRC should work without issues on LE. You'll find results like this, if you use our search function.
I can access the services without problems on my RPi. The error is related to SSL certification. Maybe you have to change router settings:

Sounds like an AVR problem (maybe too slow for 4K). Change the cabling that way:
- video: RPi -> TV (regular HDMI port)
- audio: TV (eARC HDMI port) -> AVR
eARC is made for audio transmission, so I think CEC signals are left out by design.
LE's CEC client works out-of-the-box. Make sure you have been activated CEC on your TV (External Device Manager, option Anynet+). Also check your HDMI cables, as described at your 4K thread.
Do you use 4K HDMI cables (HDMI 2.0 or 2.1 standard)? If not, then low HDMI speed can lead to a limited whitelist of HDMI modes.
Can you copy the kodi.log from microSD to your PC? If yes, upload it to Pastebin and post the link.
I am using a MariaDB docker to keep a centralized database on my Unraid servers SSD Cache Drive.
I think it's a DB issue:

VLC can stream to other VLC clients. I already did this to stream DVD from PC to an Android device, which was connected to the TV. In theory such a VLC client should work with LE, too. Maybe such an LE add-on exists, but I haven't found it yet.
We already had that feature request a couple of times: Click!
I forgot about that, but yes, it could have been SD. It wasn't Full-HD for sure.
I find references to a Sandmann79 repository. Does this still work?
I was using it last year on RPi3B+, and it worked. Navigation isn't very convenient with that add-on.
PS: Just to be sure you don't make the same error as me: Click! 
Both settings exist for RPi4B, and some users notice changes when they play with it. No idea about hardware / software implementation.
At the HiFiBerry page of the DAC2 Pro they speak about a DSP module, which can be plugged in. Eventually your DAC is configured for that non-existing DSP module, resulting in frequency errors.
Have a look at your audio device settings. Maybe you find another HiFiBerry device on the list (without DSP hardware), which plays fine.
