worker.dev not loading on cellphone/laptop when using mobile data
I'm testing out my newly built website - https://adv-ai-v30-prod.sugilaw.workers.dev/ - using Cloudflare workers and Svelte 5 - and the site loads perfectly when using wifi/fibre - but when using mobile data or whe on my cellphone - it's as if the site doesn't even exist - won't load at all. I tested the mobile connection and all other sites work perfectly - excepting mine :/

What error do you see exactly?
That's just it - nothing - it just doesn't load - at all - I looked at the network tab - and nothing! It's as if it's being completely blocked before I can even hit the cloudflare servers.
Vodacom - in South Africa
Here's a video showing how it works on wifi, then switch to mobile data - and nothing - do a test, and there's internet

Can you do a DNS lookup via dig while you are connected to mobile?
um, I can try - no idea how to - but let me chatgpt the instructions quickly
Yip - chatgpt + your "dig" pointer helped find the root cause - seems my provider - vodacom - is outright blocking "worker.dev" domains 😿
So I'll need to create an actual friendly domain to make it work - which I'm going to have to do anyway as this will eventually be a public facing site soon.
Thank you so much for the fast responses and pointing me in the right direction, truly appreciate it!
