Proxy server problem or address error | proxy connection failure troubleshooting methods and common error codes

Proxy IP connection fails, check these 3 basic items first

When encountering a proxy server reporting an error, theMake sure the proxy address and port are correct first. Many users are prone to copying and pasting directly with spaces, for example, by putting123.45.67.89:8080put down as123.45.67.89 :8080This extra space causes the connection to fail.

The second thing to check is that the protocol types match. If you use ipipgo's SOCKS5 proxy but set the HTTP type in your browser, there will be protocol incompatibility. It is recommended to check the protocol types supported by the proxy in the ipipgo backend, their full range of proxies support HTTP/HTTPS/SOCKS5 protocols.

Thirdly pay attention to the timeliness verification. The validity period of dynamic residential IP ranges from 5 minutes to 1 hour. If it is still in use beyond the validity period, the system will automatically disconnect. At this time, you can quickly verify whether the current IP is alive or not by using the "real-time status detection" function in the background of ipipgo.

Troubleshooting typical problems caused by the network environment

When theERR_PROXY_CONNECTION_FAILEDWhen this type of error occurs, it is recommended to test it with a cellular hotspot first. If you can connect normally after switching networks, it means that the original network has the following problems:

In the case of an enterprise network environment, it is also important to note thatProxy server whitelisting mechanismThe following is an example of a proxy that can only be used with a specific IP segment. Some companies restrict the use of proxies to specified IP segments, in which case you need to contact ipipgo technical support to obtain an exclusive IP segment.

5 Proxy Error Code Explanations You Must Master

407 Proxy Authentication Required
Incorrect account password or incorrect authentication method. ipipgo's proxy supports two authentication methods: username password and IP whitelist, so be careful to configure the correct authentication parameters in the code.

502 Bad Gateway
Proxy server response timeout. It is recommended to reduce the frequency of requests or switch to ipipgo's Dynamic Residential Proxy, whose intelligent routing technology automatically switches the optimal node.

CONNECT_TIMED_OUT
Local to proxy server network latency is too high. This can be accomplished by using the ipipgo providedNode Latency Test Tool, select the regional node with the fastest response time.

Why ipipgo is recommended to solve proxy problems

When encountering complex proxy connection problems, theStable pool of agent resourcesIt is often more effective than technical troubleshooting. ipipgo has 90 million+ residential IP resources and supports accurate IP filtering by region and carrier. their technical team has tested 20+ proxy anomaly scenarios and can quickly locate the following problems:

• IP blocking in specific regions
• Carrier network routing anomaly
• IP Multiplexing Limitations in High Concurrency Scenarios

Through the backend of theConnection log analysis system, users can view the specific error type and node status of each failed request, which is particularly useful when troubleshooting intermittent failures.

QA for high-frequency questions

Q: What if the proxy works but is slow?
A: First test the local network bandwidth, if normal, switch the protocol type in ipipgo background. For example, change the HTTP proxy to SOCKS5 protocol, the transmission efficiency can be improved more than 40%.

Q：Why does it prompt that the IP is restricted by the target website?
A: It is recommended to enable ipipgo'sIntelligent Rotation ModelThe system automatically replaces IPs according to preset rules, and their pool of residential proxies assigns an average of only 3 users per IP, effectively reducing the probability of banning.

Q: How to manage using multiple agents at the same time?
A: It is recommended to use ipipgo's API interface to manage proxies in bulk, which supports setting traffic alerts, automatically replacing failed nodes and other functions, and improves the efficiency of manual maintenance by more than 10 times.
