More and more websites and service providers are implementing proxy blocking technology to restrict access to their content through proxy servers. This is a big challenge for users and businesses that rely on proxies. In this article, we will explore how to identify and unblock proxy blocks so that you can continue to enjoy the convenience of proxies.

1. What is proxy blocking?

Proxy blocking refers to the use of various technical means by service providers to identify and restrict access to their content through proxy servers. These technical means include but are not limited to:

IP address detection: Detect and block the IP addresses of known proxy servers.

DNS query: Identify and block proxy traffic by analyzing DNS query records.

User behavior analysis: Identify abnormal proxy access by analyzing user behavior patterns.

Traffic fingerprinting: Identify and block proxy traffic by matching traffic characteristics.

2. How to identify proxy blocking?

Before unblocking a proxy, you first need to confirm whether you have encountered a proxy block. Here are some common proxy blocking symptoms:

Unable to access specific websites: When using a proxy server, specific websites cannot load or display error messages.

Frequent verification codes: When using a proxy, you are frequently asked to enter verification codes.

Slower access speed: When accessing a website through a proxy, the speed slows down significantly.

Abnormal account prompt: When logging in, you will receive a prompt for abnormal account activity, requiring additional verification.

3. How to remove proxy blocking

Use advanced proxy services

Many advanced proxy services offer rotating IPs, high anonymity, and multi-layer encryption, which can effectively bypass most proxy blocking measures. Choosing a reputable and technologically advanced proxy service, such as Residential Proxy or Dedicated Proxy, can increase the probability of successfully bypassing proxy blocking.

Change IP addresses regularly

Frequently changing proxy IP addresses can reduce the risk of being identified and blocked. Many proxy services provide IP rotation functions, which automatically change IP addresses, increase the diversity of proxy traffic, and reduce the chance of being blocked.

Use encryption technology

Using SSL/TLS encryption technology, you can hide the characteristics of proxy traffic, making it difficult to detect and block. Make sure the proxy service supports encryption protocols and enable these features in the proxy settings.

Obfuscate traffic

Using obfuscation technology, proxy traffic can be disguised as normal traffic to bypass traffic fingerprinting. Obfuscating Proxy and VPN obfuscation techniques such as Shadowsocks and Obfsproxy are both commonly used obfuscation methods.

Change DNS Server

Some proxy blocking techniques rely on DNS query records. By changing the DNS server, these detections can be bypassed. For example, use a public DNS server such as Google DNS or Cloudflare DNS instead of the default ISP DNS server.

Use browser extensions

Some browser extensions, such as VPN extensions or proxy extensions, can provide additional anonymity and encryption features to help bypass proxy blocking. Choose reputable extensions and update them regularly to ensure their effectiveness and security.

Avoid overuse

Excessive use of the same proxy IP address to access a large number of websites is likely to attract attention and be blocked. Reasonable distribution of proxy traffic and avoid frequent access to the same target can reduce the risk of being blocked.
