Reasons and solutions for not being able to use the network after purchasing a proxy IP

Why can't the proxy IP be used normally?Purchasing a proxy IP is an important means to improve network anonymity and break through access restrictions. However, some users may encounter problems with not being able to connect to the network after configuring a proxy IP. This situation usually stems from multiple factors, including incorrect proxy settings, network environment restrictions, or quality problems with the proxy service itself.Professional solutions provided by proxy service brands such as PYPROXY can effectively reduce the occurrence of these problems. By deeply analyzing common causes and providing targeted solutions, users can quickly restore network connections.Common reasons why proxy IP cannot be used1. Proxy IP setting errorIn many cases, the proxy IP cannot be used because of an error in the settings. For example, the IP address or port is incorrectly filled in, or the correct protocol type (HTTP, HTTPS or SOCKS5) is not enabled. In addition, some users may miss key steps when configuring the system or browser proxy, resulting in invalid proxy settings.2. Network connection problemThe proxy service needs to run in a stable network environment. If there is a problem with the local network connection, such as a weak Wi-Fi signal or abnormal broadband service, even if the proxy IP itself is valid, it cannot access the network normally.3. Proxy service provider restrictionsSome proxy service providers may restrict the scope of use of IP, such as only allowing it to be used in specific regions or devices. In addition, some low-quality proxy services may provide reused or banned IP addresses, which directly causes the proxy IP to fail.4. Target website restrictionsThe target website may implement detection and restrictions on proxy traffic. For example, some websites will identify proxy IPs and take measures to block access, especially those users who use low anonymity or public proxy IPs.5. Firewall or antivirus software blockingFirewalls and antivirus software may mark the proxy server's traffic as abnormal, thereby preventing it from running. This is particularly common in corporate networks, because corporate firewalls usually set stricter restrictions on proxy services.6. Account authentication issuesSome proxy services require users to enter an account name and password for authentication during configuration. If the authentication information is incorrect or the service is not activated, the proxy IP will not work properly.Solve the problem that the proxy IP cannot be usedCheck the correctness of the proxy settingsMake sure the proxy IP address and port number are correct, and select the appropriate protocol type (HTTP, HTTPS or SOCKS5).

JavaScript Proxies: Usage and Functionality Explained

In JavaScript, Proxies are a powerful tool that enables you to intercept and customize the fundamental operations of an object. They provide a layer of abstraction between the target object and the code that interacts with it. Proxies are often used for tasks like logging, validation, and data modification before it reaches the actual object.1. What is a Proxy?A Proxy in JavaScript is a wrapper or placeholder for another object, called the target. The Proxy allows you to define custom behavior for fundamental operations such as property lookup, assignment, enumeration, function invocation, etc. on the target object.2. Creating a ProxyTo create a Proxy, you use the Proxy constructor, which takes two arguments: the target object and a handler object that defines the traps for the fundamental operations.javascriptconst target = {}; const handler = { get(target, propKey, receiver) { console.log(`Getting ${propKey}`); return Reflect.get(...arguments); }, set(target, propKey, value, receiver) { console.log(`Setting ${propKey} to ${value}`); return Reflect.set(...arguments); } }; const proxy = new Proxy(target, handler);In the above example, we have a target object {} and a handler object with get and set traps. The Proxy constructor is used to create a new proxy object proxy.3. Proxy TrapsThe handler object can define traps for various operations. Some common traps are:get(target, propKey, receiver): Intercepts reading of a property.set(target, propKey, value, receiver): Intercepts writing to a property.has(target, propKey): Intercepts the in operator.deleteProperty(target, propKey): Intercepts the delete operator.apply(target, thisArg, argumentsList): Intercepts function calls.construct(target, argumentsList, newTarget): Intercepts the new operator.4. Using ProxiesProxies can be used in various scenarios. For example, you can use them to log all property accesses on an object:javascriptconst target = { name: 'John', age: 30 }; const handler = { get(target, propKey, receiver) { console.log(`Accessing ${propKey}`); return Reflect.get(...arguments); } }; const proxy = new Proxy(target, handler); console.log(proxy.name); // Logs: Accessing name, then JohnOr, you can use Proxies to implement validation or data modification before it reaches the target object:javascriptconst handler = {set(target, propKey, value, receiver) {if (propKey === 'age' && typeof value !== 'number') {throw new Error('Age must be a number');}return Reflect.set(...arguments);}};const proxy = new Proxy(target, handler);proxy.age = 'thirty'; // Throws an errorProxies in JavaScript provide a powerful mechanism to intercept and customize the behavior of objects. They are especially useful for tasks like logging, validation, and data modification. By defining traps in the handler object, you can intercept fundamental operations on the target object and perform custom actions before or after the operation is executed.
