Hi, I can help diagnose and fix why the educational website is not loading on your school office Wi-Fi while working correctly on mobile data or external networks. The best solution is to first test DNS resolution, firewall logs, proxy/content-filter rules, SSL inspection, routing, VLAN policies, and browser/network errors from inside the LAN/WLAN. Once the exact failure point is identified, I’ll guide or apply the correct change without weakening your existing security setup. I’m comfortable with DNS troubleshooting, firewall rule review, content filtering, proxy checks, SSL inspection issues, router/Wi-Fi controller diagnostics, Linux/network tools, packet tracing, and school/office network support. Deliverables will include: * Root-cause identification * DNS/firewall/proxy checks * Content filter review * SSL/routing/VLAN verification * Corrective configuration guidance * Testing across multiple devices * Confirmation that the site loads on Wi-Fi * Short documentation of the fix Preferred tools: nslookup/dig, ping, traceroute, curl, browser dev tools, firewall logs, DNS logs, and packet capture if needed. Estimated timeframe: same day or within a few hours after access/details are provided. Best regards Ankit

A few quick questions: What firewall/router are you using (FortiGate, MikroTik, pfSense, Cisco, UniFi, etc.)? What is the website URL that isn't loading? Do you have remote access available for the firewall or controller? Have any recent network or security changes been made? I can start immediately and expect the initial diagnosis within 1–2 hours.

Hello, I am a network specialist and systems administrator with experience in diagnosing and resolving connectivity issues in educational and corporate environments. I have identified that the blocking of a specific website within the LAN/WLAN network, affecting all devices equally, is a classic symptom of a filter applied at the network level — whether by firewall, DNS, SSL inspection, or proxy — and not a problem with the users' devices. My approach is methodical and results-oriented: I will identify the exact point of failure, apply the corrective solution, and leave you with a documented summary for future reference.

Hello, I can help you quickly diagnose and resolve the issue preventing access to your educational website on the school Wi-Fi network. Since all devices experience the same loading timeout on the local network while mobile data works seamlessly, this is definitely a network-side blocking or filtering issue within your LAN/WLAN infrastructure. My Systematic Troubleshooting Approach: DNS & Resolution Check: Verify if the school’s internal DNS server or upstream DNS filter (e.g., Cisco Umbrella, Pi-hole, Cloudflare) is failing to resolve or sinkholing the new domain. Firewall & UTM Inspection: Review traffic logs on your router/firewall (e.g., Fortinet, PfSense, SonicWall, Sophos) to see if port 80/443 traffic to the IP is being dropped or flagged. SSL Inspection & Proxy Policies: Check if deep packet/SSL inspection is blocking the domain's certificate or if an outbound proxy rule is timing out. Routing & MTU Settings: Ensure there are no asymmetric routing issues or MTU path bottlenecks across VLANs. Deliverables: Clear identification of the exact root cause. Implementation of the fix (or step-by-step guidance for your local admin). A concise technical document summarizing the root cause and configuration changes made for future reference. I am available to start immediately via remote session (AnyDesk, TeamViewer, or SSH/Web UI access). Looking forward to resolving this for you!

@kumarsanjeeb797

Hi [Client Name / Hiring Manager], Here’s my take: This issue is almost certainly caused by DNS filtering/sinkholing, an overly strict firewall policy (or Web/Content Filter blocking a new domain's reputation score), or SSL Inspection/SNI blocking on your school's network edge. Since new educational domains often lack an established reputation score, security filters frequently flag or drop them by default. I can help you pinpoint the exact root cause in less than 30–60 minutes and implement a clean, permanent solution that keeps your school's security intact.

@EkikaranIT

Hi, The pattern you've described — identical failure across laptops, and phones, but working fine off-network — rules out device/browser issues and points squarely at something in your LAN's filtering layer, not the router or ISP link itself. My strong first suspicion: many content filters and firewalls auto-block domains categorized as "uncategorized" or newly registered" by default policy — which is exactly the situation for a brand-new educational site that hasn't been indexed/categorized yet by your filter's threat-intelligence feed. This is one of the most common causes of "one specific new site won't load, everything else does. My diagnostic approach: • Confirm DNS resolution for the domain from inside vs. outside your network • Check firewall/content filter logs for the specific domain — looking for a category-based block, not just a manual blacklist entry • If SSL inspection is enabled, check whether the new site's certificate is failing inspection (another common cause for new domains specifically) • Review proxy config and VLAN routing if the above doesn't isolate it Deliverables, matching what you outlined: • Exact point of failure identified (device/rule/service) • Fix implemented directly • Short written documentation of the change for your records I'm comfortable working via remote access to your firewall/controller. What firewall/content filter platform are you running? That'll let me confirm my approach before we start.

Hello, I read your project details carefully, and I completely understand the network-side issue you are facing with your school's Wi-Fi blocking the new educational website. Since the site works perfectly on mobile data, the root cause is definitely related to DNS misconfigurations, router firewall rules, or content filtering policies on the local network infrastructure. As a certified networking and security specialist, I am fully equipped to fix this immediately: * I hold a professional certification from the Cisco Networking Academy, specializing in Routing, Switching, and Network Administration. * I am currently Ranked #1 in Bangladesh on the TryHackMe Leaderboard (Top 5% Globally) for enterprise infrastructure and network troubleshooting. * I master network diagnostics, DNS routing, and firewall log inspections to isolate transport layer blocks. I will safely guide you or your staff to analyze the router's DNS settings, check the local content filters/IPS rules, and resolve the loading error so everyone can access the site seamlessly. I accept your budget and can resolve this within a few hours today. Let's connect in chat to get your school Wi-Fi fixed right away!

Hello, I can help diagnose and resolve this issue quickly. Based on your description, the problem is likely occurring at the network layer since the website works on external networks but fails consistently on your office Wi-Fi across all devices. I've worked with enterprise network environments involving firewalls, VLANs, DNS, VPNs, and wireless infrastructure, and have experience troubleshooting issues related to DNS resolution, SSL inspection, content filtering, NAT policies, routing, and access control.

@mcagmel

Hi, I’m a telecommunications/network engineer and this issue can be approached systematically by comparing the failing school network path with a working external connection. I would first verify DNS resolution and reachability from the school LAN, then isolate whether the failure occurs at DNS/content filtering, firewall policy, proxy, SSL inspection, routing, or another network layer. I can troubleshoot remotely with you, identify the root cause, guide or implement the corrective change, and provide a short summary of the issue and resolution afterward. Since the website works from external networks and the issue affects multiple devices on the school network, I would focus on the shared network infrastructure rather than individual clients. I am available to start immediately.
