Why Do Websites Block VPNs? 5 Reasons and What You Can Do

Websites block VPNs because many people share the same VPN server address, so a site cannot tell one careful user from thousands of others or from automated traffic. The block usually shows up as an error page, a login that keeps failing, or a captcha on every visit. Switching server, protocol or moving to a dedicated IP address fixes most cases.

Why do websites block VPN addresses?

Websites block VPN addresses mainly to fight fraud and automated traffic. A normal home connection has an address used by one household. A shared VPN server address is used by many people at once, and if even a few of them send spam or try stolen passwords, security services mark the whole address as risky. Every other person on that address then sees the same block.

What are the 5 most common reasons for a VPN block?

Shared address reputation. Many users on one address; one bad actor taints it for everyone.

Fraud checks at banks and shops. A login or payment from an address in a data centre, or from a new country, looks like account takeover.

Content licences. Streaming services must show different libraries per country and block addresses they cannot place.

Bot protection. Captcha services score data-centre addresses lower than home addresses, so you see more puzzles.

Local network rules. Some schools, offices and countries block VPN connections themselves, before any website is reached.

How do you get past a website that blocks your VPN? 5 fixes

Switch to another server location in the app. A different address may have a clean record.

Pick a server in the country of the account, for example your home country for your bank.

Change protocol. If the network blocks one VPN protocol, another may get through.

Clear the site's cookies and log in again after changing server.

Use a dedicated IP address. A dedicated IP is an address only you use, so its reputation is yours alone.

What is a dedicated IP and why does it help?

A dedicated IP is a VPN address given to one customer instead of shared with many. Because nobody else uses it, banks, shops and work systems see the same familiar address every time you log in, and captchas become rare. It also lets an office allow-list your address. The trade-off: activity on a dedicated IP is easier to link to one person than activity on a shared address. Read What is a dedicated IP address, and do you need one?

Does CasperVPN offer a dedicated IP?

Yes. CasperVPN Premium includes every server location and all protocols, and a Dedicated IP is available as an optional add-on. Current prices are on the pricing page. The free plan (0.5 GB a month, no credit card) is a good way to test whether a shared server already works for the site you need.

FAQ

Is it illegal for a website to block a VPN?

No. A website may decide which addresses it accepts. A block is a security or licence choice, not a sign you did anything wrong.

Why do I get a captcha on every page with a VPN?

Captcha services rate shared VPN addresses as higher risk. Switching server or using a dedicated IP usually reduces them.

Will a dedicated IP work with every website?

No one can promise that. A dedicated IP removes the shared-reputation problem, but a site that blocks all VPN or data-centre addresses may still block it.

Should I turn the VPN off for my bank?

Only on a network you trust, such as your home Wi-Fi. On public Wi-Fi, connect to a server in your home country instead.
