Proxy is a concept that is no longer unfamiliar to many people, especially in the field of IT and network security. But really, what is a Proxy, and how does it work? Please explore the details through the article below.
Introduction to Proxy
First of all, to put it simply, a Proxy functions like a “middleman”, standing between your computer and the internet. Whenever you access a website or an online service, instead of connecting directly, your computer will connect to the Proxy, and then the Proxy will continue to connect to the destination you want to access.
One of the main benefits of using a Proxy is improving online security and privacy. When accessing the internet through a Proxy, your real IP address will be hidden and replaced with the IP address of the Proxy. This means that websites and online services cannot determine your real location, helping you browse anonymously and avoid security threats.
In addition, Proxy also helps increase internet access speed. Proxy services often store a copy of frequently visited websites in their cache. This reduces page loading time, increases access speed, and provides a smoother browsing experience.
However, not all Proxies are the same. There are various types of Proxies with different purposes and applications. For example, traditional Proxies are mainly used to improve access speed and security, while reverse proxies help with load balancing and optimizing performance for large online services. There are also Proxies specifically for accessing blocked websites or bypassing geographical restrictions.
While Proxy offers many benefits, users must be cautious when selecting and using Proxy services. Not all Proxy services are safe and reliable. Sometimes, using a Proxy of unknown origin may put you in danger, as your personal information and data could be monitored, collected, and used for malicious purposes. Therefore, before deciding to use a Proxy service, you should research thoroughly and choose reputable, highly-rated services from the community.

Bandwidth Limiting
Ability to limit access speed for specific users or services.

How to Fix Can’t Connect to Proxy Server Error
Step 1: Check Proxy Settings
Open browser or system settings. Find the network or proxy settings. Ensure you have correctly configured the proxy server information. If you don’t want to use a proxy, turn off this feature.
Step 2: Check Security Software
Sometimes just turning off and restarting the browser can solve the problem. Make sure you have a stable internet connection. Sometimes, the problem is not the proxy but an interrupted internet connection. Some antivirus software or firewalls may block connection to the proxy server. Check and reconfigure if necessary.
Step 3: Update Browser
Make sure you are using the latest version of the browser. Some users have resolved this issue by using a different DNS service like Google DNS or Cloudflare DNS. If you are using a proxy service, try switching to another proxy server.
Step 4: Restart Computer
Sometimes, restarting can solve many technical issues. If you are using a paid proxy service, contact the provider for more details about the issue. On some operating systems, proxy settings can be applied system-wide, not just in the browser. Make sure these settings are not causing problems.
