The greatest thing about this implementation is its simplicity. I actually deployed this server for my personal use because everything lives in one Docker image and not a lot of them like the official implementation. I do understand that the official implementation helps with scalability and more, I just don't need it.
It's so sad how people need to expose the issue publicly to actually get human help (sometimes!). Support at Google's scale takes a lot of human resources, I get it - but come on, how hard can it be?
P.S.: Best of luck in getting this issue resolved!

Edit: I just noticed your OpenGraph URL points to https://next-tails.vercel.app when the URL is https://nextails.com. Maybe that's an issue? Maybe not OG itself but some meta tag or something similar?
If you don't mind going a little deeper on this, what program do you use to run your VM? Do you only access your VM via SSH? What kind of development do you do? Do you have an internal IP for your VM or do you just redirect the ports?
Do you think you could replace your VM with Bash on Windows?
