I have tried both of those code snippets separately in my functions.php file with no luck. Any other ideas?

I can see how to use this for pages on my website, but how would I whitelist all of REST API? I do not have URLs for them, as it all behind-the-scenes through a plugin I use

Could I maybe whitelist a certain IP address? Is that possible?

No, it works perfectly fine once Force Login is disabled

On a separate testing server, I was able to have it work with the code you gave.
However, using the code from the main server, it gives the same issue. Can you see any issues with the code used?
