šŸ’” Why your VPN suddenly stops working — real reasons South Africans see

Most of us fire up a VPN, expect the little lock to appear, and carry on. Then — poof — it drops, speeds tank, or a streaming site still blocks you. Annoying? Absolutely. Dangerous? Sometimes. You use a VPN for privacy, work, or to catch the latest show while travelling — and when it fails, you want answers fast.

This guide is for the person in Cape Town, Joburg, Durban or anywhere in SA who needs a practical, step‑by‑step fix. I’ll walk you through the common culprits (app glitches, ISP throttling, server bans, DNS leaks, router issues), a quick test checklist, and hands‑on fixes you can try right now. Expect useful local tips — like checking your mobile data settings on MTN/Vodacom or testing from a family‑friend’s Wi‑Fi — and clear next steps if the problem needs support from your VPN provider.

By the end you’ll know how to verify whether the VPN is actually active, how to test for leaks, when to switch servers or protocols, and how to decide if the VPN itself is the problem or just your connection. No fluff — just the checks that work for folks here.

šŸ“Š Quick health-check table for your VPN (device vs problem)

šŸ§‘ā€šŸ’» DevicešŸ”§ Most common issuešŸ› ļø Quick fixā±ļø Typical time to fixšŸ“ˆ Success rate

This table shows where most problems live: phones fix quickly (battery settings), routers take longer, and streaming blocks are hit‑and‑miss. The success numbers are practical estimates: user fixes on phones or laptops usually work fast, while router and SaaS issues often need reconfiguration or support help.

If you’re trying to stream a show and the VPN appears connected but the platform still blocks you, the next step is to test another server in the same country — many providers rotate IPs and maintain specific ā€œstreamingā€ servers for that reason. For general privacy checks, always run an IP and DNS leak test after reconfiguring anything.

šŸ’” Hands‑on checklist: 12 things to try right now

Start here — these are fast, local-friendly checks that fix most problems.

  1. Check basic internet: Can you load a non‑HTTPS page or run a speedtest without VPN? If no, fix network first.

  2. Verify the VPN is really connected: Visit an IP-check site and confirm the IP and country changed. The router‑verification tactics from our reference apply — try a geoblocked catalogue or a simple IP check after configuration.

  3. Check subscription & app updates: Ensure your plan’s active and the app is up to date.

  4. Restart devices and router: Classic, but often effective.

  5. Change server: If streaming’s blocked, try a nearby server or a provider’s ā€œstreamingā€ tag. If speeds are bad, try a closer server.

  6. Switch protocol: Try WireGuard (fast) or OpenVPN TCP/UDP. Some ISPs throttle particular protocols.

  7. Test for DNS leaks: Run a leak test. If your ISP shows up, enable the provider’s DNS or use 1.1.1.1 / 9.9.9.9.

  8. Disable split tunnelling temporarily: If some traffic is bypassing the VPN, that could explain leakage.

  9. Check firewall / antivirus: Allow the VPN app or temporarily disable firewall for testing.

  10. Check date & time: Wrong system time can break TLS and prevent connections.

  11. Try a different network: Connect via a hotspot or neighbour’s Wi‑Fi to isolate ISP blocks.

  12. Reinstall the app and clear cache: Corrupted files can cause connection failures.

If your VPN previously worked on a router, re-check the router settings: a changed public IP, expired certificate, or wrong login credentials will kill the route. You can validate router VPN operation by checking if multiple devices behind it show the changed IP and can reach geoblocked content — the same techniques in the reference material are useful here.

šŸ› ļø Deeper causes and fixes (read if the checklist didn’t help)

Sometimes the issue is obvious (expired subscription), sometimes it’s subtle (ISP or platform countermeasures). Here’s what usually hides under the hood.

  • ISP throttling or routing problems: Some ISPs deprioritise VPN traffic or route you poorly. If speeds are bad only with the VPN, test several server locations and protocols. If your ISP is the bottleneck, switching to WireGuard or a nearby server often helps.

  • Platform blocks and IP blacklists: Big streaming services detect and block shared VPN IPs. They update filters all the time — that’s why you might see a show blocked today and available tomorrow on a different server. Streaming guides like the one for catching geo‑locked documentaries show how rotating servers and provider streaming lists are useful for viewers [tomsguide, 2025-08-26].

  • Malicious or buggy browser extensions: Some extensions capture screenshots or act as man-in-the-browser agents, which can interfere with VPN behaviour and privacy. A recent investigation warned about Chrome extensions taking screenshots without clear user consent — good reminder to audit your extensions if things go sideways [technologijos, 2025-08-26].

  • Legal and compliance filters: New rules around age verification or platform access may push services to tighten IP-based access. Reports show proposals that would change how some VPNs handle user identity in certain markets; that’s an emerging trend to watch if you rely on a VPN for content access [macg, 2025-08-26].

When you hit platform or policy walls, support is your friend: send your VPN provider the exact error, server name, timestamps, and any streaming error codes. Good providers can switch you to working IPs or suggest server groups that still work for streaming.

šŸ™‹ Frequently Asked Questions

ā“ Why does my VPN sometimes slow my connection?

šŸ’¬ VPNs add encryption and routing overhead; expect a moderate speed drop. If speeds are very low, switch servers, use WireGuard, or pick a closer server. Also check for carrier throttling — mobile networks sometimes limit encrypted traffic.

šŸ› ļø My VPN connects but websites still see my real location — what now?

šŸ’¬ This is likely a DNS leak or split tunnelling. Run an online IP/DNS leak test, enable the kill switch, and force the VPN DNS. If the leak persists, reinstall the app and test again.

🧠 Can I trust free VPNs to fix this or are paid services better?

šŸ’¬ Free VPNs often have limits or risky data practices (some have been found to share user data or embed tracking). For reliable streaming, privacy, and support, paid providers are a far better bet.

🧩 Final Thoughts…

If your VPN stops working, don’t panic. Start with the basics: verify the connection, test IP/DNS, try a different server, and switch protocols. Phones usually fix quickly (settings), routers take more elbow grease, and streaming blocks need server rotation or provider help.

Keep a small checklist on your phone: test IP, run a leak test, switch server, then contact support with logs if you’re stuck. Small tweaks often get you back online fast.
