Why Your Website Loads on Mobile Data but Not on Wi-Fi

It might seem weird that your website loads fine on mobile data but not on Wi-Fi, and the issue often points to your Wi-Fi router's DNS settings or firewall rules. Mobile data uses your carrier's DNS, which may bypass restrictions, while your home network might be blocking certain requests or using a slow DNS server. Try flushing your DNS cache or temporarily switching your router's DNS to a public one like Google's to test if that fixes it.
