I'm experiencing a strange networking issue that seems connected to Indian ISPs. Here's my setup: I use a Hostinger VPS with Coolify for the backend, linked to a subdomain, while my frontend is hosted on Vercel with a main domain. I've noticed that on certain WiFi networks, my frontend works without a hitch, but all API calls to the backend fail. Interestingly, when I switch to mobile data, everything functions perfectly. Testing other devices on the same WiFi yields the same errors, and at one point, I couldn't even access the Hostinger website itself. This seems to happen temporarily and then resolves on its own. It seems like Indian ISPs might be blocking Hostinger's datacenter IPs on some networks. Have others faced this issue too? I've seen online discussions about ISPs blocking VPS IPs, but this feels a bit extreme. I'm considering a few potential solutions like using a Cloudflare proxy, requesting a new IP, or even switching to a different VPS provider that's more reliable in India. I'd love to get your insights on this!

Seems like Hostinger's VPS service comes with a side of ISP blocking! A Cloudflare proxy is a solid move; their infrastructure is generally reliable, so that could help you avoid those blocks. But yeah, you might find yourself in a game of IP roulette with Hostinger until you land an unblocked IP.
If you're looking to avoid these issues going forward, switching to a VPS provider known for having better IP reputation in India could save you a lot of headaches. It's frustrating when ISPs get involved like this, but you have options to work around the problem!
It's worth considering that it might not just be the ISP blocking the IP; it could also be specific to the WiFi network or router settings causing these issues. Have you double-checked the network configurations? Sometimes it's not as clear-cut as we think!

Good point! I initially thought it could be something like that, but I've tried it on different routers and still faced the same issue. That’s why I’m thinking it may lean more towards ISP-related filtering.
