Can you describe a bit more? What HTTP error codes are they receiving? Are there any errors in your deployment logs?

We’re not seeing any logs in the console, but the request times out with a ‘took too long to respond’ error. The API works correctly when accessed using a VPN from another country. It was functioning earlier and stopped recently

Does it still work with a VPN? Or does it time out now?

The APIs are not working from Pakistan, but they work correctly from other countries,
I’ve attached a screenshot showing the API response when accessed from Pakistan.

pakistan is likely blocking .up.railway.app ; This isn't a Railway issue Railway cannot do anything about ISP-level blocks imposed by local firewalls, so you should add a custom domain (cname to your service) and front it with cloudflare so traffic bypasses the ISP-level block; that’s why you see no logs

used custom domain

then pakistan is blocking or dropping the traffic at isp level (dns/ip/dpi), so it never reaches railway. proxy the domain through cloudflare (orange cloud on, different dns / edge) or it’ll keep timing out; vpn works because it exits pakistan first

My project has been hosted for the past three months and was working fine in Pakistan during that time. This issue started only today, which is why I’m confused

Hello,

ilyassbreth is correct, your ISP is blocking you, not Railway. Unfortunately, there is nothing we can do on our side about the firewalls you are behind.
