Proxy IP tool connection failure? Five common error code solutions

In the process of using proxy IP, have you ever encountered sudden disconnection, web page loading failure or even pop up a string of unintelligible error codes? Don't panic! This article will focus onTop 5 High Frequency Error Codes, hands-on troubleshooting with a combination ofFeatures of ipipgo proxy serviceGive targeted solutions.

I. Error code 407: Authentication failure

Misperformance:When connecting to the proxy, it prompts "Proxy authentication is required", and I can't log in even though I repeatedly enter my account password.

Core reason:Incorrect username/password or mismatch of authentication methods. Some proxy services use dynamic key authentication, traditional fixed passwords may not work.

Solution: 1. Check the ipipgo console for up-to-date authentication information, noting thatDynamic keys are automatically refreshed every 15 minutesCharacterization 2.Automatic Authentication Protocol(e.g. Socks5 with encryption) instead of manual input 3. Configure whitelisted IPs in the code to be automatically released to avoid frequent authentication

II. Error code 403: request prohibited

Misperformance:I can connect to the proxy, but when I access the website, it says "No permission to access".

Core reason:The target website has blocked the current proxy IP, which is common for repeated high-frequency operations using the same IP.

Solution: 1. Enabling ipipgoIntelligent Rotation ModelIf a single session is not completed, it will automatically switch 3-5 residential IPs. 2. Set the access interval time, it is recommended that e-commerce business ≥ 30 seconds/time, social media ≥ 5 minutes/time. 3. Combine the use of mobile+home broadband IPs, to reduce the probability of recognition.

III. Error code 502/504: Gateway timeout

Misperformance:Gateway Error" or "Connection Timeout" is displayed after a long time loading.

Core reason:The link between the proxy server and the target website is unstable, which is common in cross-country access scenarios.

Solution: 1. Switching in the ipipgo backgroundDedicated acceleration nodesIf you want to use a proxy that is in the same region as the target server, you must select one that is in the same region as the target server. 2. Adjust the timeout threshold to 15-30 seconds (the default is 10 seconds, which is easy to trigger a timeout). 3. Use a long TCP connection instead of a short one to reduce the number of handshakes.

IV. Error code 429: too many requests

Misperformance:Suddenly inaccessible with "too many requests".

Core reason:Single IP concurrency exceeds the site limit threshold.

Solution: 1. Adoption of ipipgoconcurrent pooling functionAutomatic allocation of multi-IP loads 2. Setting request queue interval randomization (recommended ±20% baseline interval) 3. Important service configurationsVIP Exclusive ChannelEnjoy a separate pool of IP resources

V. Connection completely failed: base setting error

Misperformance:The proxy tool shows no connection and cannot initiate any requests.

Core reason:The 90% stems from base configuration errors, including:
