Proxies are a common solution when we need to access restricted or blocked websites. It achieves the purpose of accessing restricted websites by passing our requests through an intermediate server. However, sometimes we find that the network cannot be used after setting up the proxy. What is the reason?

How should this problem be solved? How to prevent this from happening again? This article will answer them one by one for you.

The essence of a proxy is to forward requests through an intermediate server, so when we set the proxy to an unavailable server, network problems will occur.

In addition, if the proxy server is configured incorrectly, the network cannot be connected.

Another possibility is that the proxy server is too slow, causing the network speed to slow down or the network to time out. In this case, we may need to change to a faster proxy server.

How to solve the problem that the proxy network cannot be used?

Check the configuration of the proxy server

First, we need to confirm whether the address and port of the proxy server are correct. Under Windows systems, we can check the proxy server configuration by following these steps:

a. Open the Control Panel.

b. Click "Internet Options".

c. Select the "Connections" tab.

d. Click "LAN Settings".

e. Check that the settings in the Proxy tab are correct.

Under Mac OS systems, we can check the proxy server configuration by following these steps:

a. Click "System Preferences."

b. Click "Network".

Select the network connection currently in use.

c. Click "Advanced".

Check that the settings are correct in the Proxy tab.

If the settings are incorrect, we need to reset the proxy server address and port.

If the proxy server is configured correctly but you still cannot connect to the network, we may need to change the proxy server. We can find some public proxy servers through search engines, or purchase some paid proxy services.

Please note, be careful when using public proxy servers as these may have been abused or blocked. Additionally, the quality and speed of paid proxy services may be better, but they also need to be chosen carefully.

The firewall may block the proxy server connection, so we need to check whether the firewall settings are correct. Under Windows systems, we can check the firewall settings by following these steps:

a. Open the Control Panel.

b. Click on "Windows Defender Firewall".

c. Select "Allow app through firewall."

d. Click "Change settings."

Confirm that the proxy server application is allowed through the firewall.

Under Mac OS systems, we can check the firewall settings by following these steps:

a. Click "System Preferences."

b. Click "Security & Privacy."

c. Select the Firewall tab.

d. Confirm that the proxy server application is allowed through the firewall.

If the proxy server application is blocked by the firewall, we need to allow it through the firewall, or temporarily turn off the firewall for testing.

Sometimes, we only need to restart the network connection to solve the problem of proxy http causing network unavailability. Under Windows systems, we can restart the network connection through the following steps:

a. Open the Control Panel.

b. Click "Network & Internet."

c. Select Network and Sharing Center.

d. Click "Change Adapter Settings."

e. Right-click on the network connection currently in use.

f. Select "Disable".

Wait a moment and then right-click the connection.

Select Enable.

Under Mac OS systems, we can restart the network connection through the following steps:

a. Click "System Preferences."

b. Click "Network".

c. Select the network connection currently in use.

d. Click "Advanced".

Select the "TCP/IP" tab.

Click "Renew DHCP Lease".

Check the availability of the proxy server

Sometimes, we will choose some unreliable proxy servers, causing the network to be unstable or unable to connect. We can check the availability of proxy servers through some online tools.

If the proxy server is unavailable or the response time is too long, we should choose another proxy server or try other solutions.

How can I avoid this happening again when using a proxy service?

In order to avoid network failure when using proxy services, we should pay attention to the following points:

(1) Choose a reliable proxy server

We should choose some reliable proxy servers, such as some reputable proxy service providers, to ensure the stability and high speed of our network connection.

At the same time, we can also check the availability of proxy servers through online tools to avoid choosing unavailable proxy servers.

(2) Check the proxy server settings

When setting up the proxy server, we should confirm whether the address and port of the proxy server are correct to avoid being unable to connect to the network due to configuration errors.

(3) Test the speed of the proxy server

When choosing a proxy server, we should test the speed of the proxy server to avoid choosing a proxy server that is too slow, causing the network to time out or slow down.

(4) Close unnecessary proxy services

If we do not need to use the proxy http service, we should turn off the proxy service to prevent the proxy service from occupying network bandwidth and resources.

(5) Avoid using free proxy services

Free proxy services are usually slow, unstable, unsafe, and easily exploited by hackers. We should choose some paid proxy services to ensure network security and stability.

(6) Regularly update the proxy server

We should update proxy servers regularly and avoid using proxy servers that have been blocked or unstable.

When using proxy services, we need to pay attention to the selection, configuration, speed and availability of the proxy server, as well as firewall settings and network connections to avoid network instability or inability to connect.

If the network cannot be connected, we can solve the problem by checking the settings of the proxy server, restarting the network connection, checking the firewall settings, and checking the availability of the proxy server. The ultimate goal is to ensure a stable and high-speed network connection and ensure that we can access the Internet normally.
