VPN Blocked? Here’s What to Do

VPNs are blocked for many reasons and in many ways, but there are just as many ways to unblock a VPN too. 

VPN Blocked? Here's How to Unblock It

Is your VPN blocked? Don't panic. Unblock it with these tips.

A good VPN can be an excellent tool for enhancing your privacy and security. It can help you with many tasks, like bypassing restrictions on your favorite streaming services and even saving you money on your next vacation.

But what happens when you load up your VPN and realize that your web traffic is blocked – or just really, really slow?

Your VPN is probably blocked, but don’t freak out. We’re going to show you how to unblock your VPN.

Why Your VPN is Blocked

First things first, it’d help to actually know why your VPN is blocked. And there are a few possibilities.

1. Pay-to-Use Wifi

It’s bad enough that airlines and hotels charge so much for WiFi, but they also tend to block VPNs. Because otherwise you’d just stream Netflix instead of paying for their overpriced in-flight movies, and they can’t have that.

2. Employers

Surprise, surprise, your boss doesn’t want you spending all day on Reddit, social media, or looking at stuff that’s not safe for work (you know what we’re talking about).

Some employers also want to know everything you do online while at work, to the extent of reading your emails and more. Since a VPN makes you harder to monitor and allows you to bypass website blocks, they’ll try to block you from using a VPN entirely.

3. School Administrators

Schools and colleges control your Internet access for many of the same reasons as employers. And they’re even more serious about inappropriate content, since they are committed to providing their students with a safe environment.

But a VPN makes it all too easy for savvy students to access their favorite websites, from gaming forums to meme pages and everything in between, all from the comfort of the campus library. So, it’s in your school’s interest to block VPNs.

4. Streaming Services

Many people have figured out that you can use a VPN to access more content through your favorite streaming services, like Netflix and Hulu. Maybe because we’ve been writing about it for years. :-/ 

But these businesses aren’t able to maximize profits when you do this, so streaming sites have become increasingly interested in blocking VPNs too.

5. Governments

Countries like the United Arab Emirates (UAE), China, and Iran are among the biggest state censors of the internet, and since a VPN would help get around their restrictions, it makes sense that they’d want to control VPN use as well.

If you’re in one of these countries, it’s pretty much a guarantee that your VPN will be blocked.

How Your VPN is Blocked

Now that we know why your VPN is blocked, let’s look at how VPN blocks are put in place.

Deep Packet Inspections (DPI)

One of the most common – and unfortunately the strongest – forms of VPN blocking is something known as deep packet inspection, or DPI.

In short, deep packet inspection is a way of, well, inspecting your Internet packets as they travel between your computer or Internet-enabled devices and the Internet-at-large.

Although a VPN encrypts your Internet traffic, meaning the state censors won’t be able to see the actual contents of the packets, they will be able to see that you’re using a VPN in general – and block it.

IP Blocking

Another common tactic is to block a VPN’s known IP addresses. This is an easier block to implement, but it’s not as effective as DPI, since there are thousands of IPs addresses among the various VPN services, making it difficult to block them all. 

Plus, VPN services are always adding new IP addresses, so this type of VPN blocking is like a game of cat and mouse or whack-a-mole.

Port Blocking

There are certain ports used primarily by VPN traffic, with 1194 being the most common. Blocking these ports altogether will block any VPN that’s using them too.

Blocking VPN Websites

The most basic form of VPN blocking is blocking the VPN websites themselves, which will stop you from subscribing, logging into your account, and/or downloading their software.

Of course, this doesn’t matter at all if you’ve already got a VPN on your device, and there are other ways to run a VPN on your school or library’s computer without downloading it online.

How to Unblock Your VPN

Okay, enough background. Let’s talk about what you really came for, how to unblock your VPN.

Use Your Mobile Device

If you just need to check Facebook or Reddit and you have a mobile data plan on your smartphone, the easiest option is to simply use your phone/tablet – or even create a mobile hotspot with your phone to connect to.

This isn’t the most robust option, but it’ll save a lot of people some trouble, especially if they just need a quick fix for overcoming a Wi-Fi hotspot that’s blocking their VPN.

Change Servers/VPNs

If your VPN is only being blocked by IP address, unblocking could be as simple as changing servers.

If all of your VPN’s IP addresses seemed blocked, you could consider trying another VPN entirely. Many VPN services offer a free trial (or money-back guarantee period) if you want to try-before-you buy and make sure it is not blocked for the purposes you have in mind. 

Change Ports

While some ports may be blocked to stop VPN use, they can’t block them all – or there wouldn’t be any Internet access. One of the most commonly used ports you could try, 443, is for HTTPS traffic, like online shopping and banking.

Your VPN traffic is already encrypted, but by routing it through port 443, it’ll be encrypted by SSL too, which makes it harder to block and even for DPI to detect.

Changing port's is easy in PIA for unblocking your VPN.

Fortunately, the best VPN providers make it easy to change ports. Some even have dedicated servers that use port 443.

For example, in the Windows VPN app for Private Internet Access, go into its Settings (see screenshot). You’ll see the item Remote Port with a drop down list. “Hey, I selected it but don’t see Port 443!” Chill. 

Choose Connection Type TCP. Once you do that, you’ll see 443 in the Remote Port drop down list. 

You can check out PIA's detailed instructions and video on the subject. Note: These instructions are for Windows, but they have guides for Mac, Android, iOS, and Linux as well. 

Use Stealth VPN Technology

If changing your port doesn’t work – or you just want the easiest and most foolproof solution to beat a VPN block – we’d recommend investing in a VPN with “stealth” technology.

With the push of a button, your VPN use will no longer be detectable by DPI.

A few of our favorite VPNs include Stealth VPN technology:

Use VPN with The Onion Router

Now, there is another option similar to using a Stealth VPN, and that’s running your VPN with Tor, The Onion Router. But there’s a catch. Your connection will be even further routed around than using a VPN alone, causing a noticeable decrease in your Internet speeds.

If the other tricks didn’t work or you’re interested in maximum privacy, VPN with Tor can be achieved with obfsproxy, but it’s a little complicated. The easier option is to switch to a VPN that has this feature built in.

Here are a few VPN services to choose from that have an Onion Router over VPN option :

Is it Illegal to Unblock Your VPN?

In the vast majority of cases, it’s not illegal to unblock your VPN. The biggest exception is the UAE, where all VPN use is illegal and punishable by huge fines – and even the possibility of prison time. So be careful if living or travelling there.

Of course, while it may be perfectly legal to unblock your VPN at work or school, there’s a risk you could still be disciplined for doing so.

Maybe it’s just a slap on the wrist, but termination or expulsion could be possibilities, depending on your employer or school. So keep this in mind.
