Quick update: this should be fixed now. It was an overly aggressive CrowdSec rule blocking some legitimate traffic.

If anyone still has issues accessing velxio.dev, let me know

Nice one! I can access it now.

Really awesome project, it runs well on my old android phone, the fact that I can use a tool like this on my phone is pretty wild, you have done well with the UI in that regard. The oscilloscope is a really nice feature too.
