I build my website using Zola, which worked pretty good. However I wasn’t satisfied with the existing templates so I did build my own using DaisyUI. That also worked pretty good most of the time and was a pleasant experience!
I can recommend the book Daemon which explores that Idea
Disable your mobile network and try again. I had the very similar issue where it would always fallback to the mobile network for local IPs although WiFi was connected and in the same subnet
Another idea if you are willing to spend some money is to get a yubikey. Then the tokens are stored on a separate hardware key and it has great android and Linux apps to access codes
