Proxy IP Blocked? | Causes and Solutions

Why Proxy IPs Get Blocked and How to Fix It #

When using proxy IPs to access certain websites, you may encounter blocked IPs, 403/429 errors, or frequent CAPTCHAs. Below are the common causes and practical solutions.

1. Why Do IPs Get Blocked? #

• Too many requests — Sending a large number of requests from the same IP in a short time
• Abnormal behavior patterns — Browsing speed far exceeding normal human behavior
• Multiple accounts on one IP — Logging into several accounts using the same proxy IP
• Low IP reputation — The IP was previously abused by other users (common with shared proxies)

2. Use Dynamic Residential IPs with Auto-Rotation #

This is the simplest and most effective solution. Jibao Proxy‘s dynamic residential IPs assign a new IP address for every request automatically — even if one IP gets blocked, the next request will use a fresh one.

Best for: web scraping, bulk operations, and any task requiring frequent IP rotation.

3. Reduce Request Frequency #

• Add random delays between requests (2–5 seconds recommended)
• Avoid hitting the same page repeatedly in a short window
• Mimic natural human browsing behavior

4. Switch IP Type #

If your datacenter IPs are getting blocked frequently, consider switching to residential IPs or mobile IPs — these carry higher trust scores and are much less likely to be flagged.

5. Use an Antidetect Browser #

If you manage multiple accounts, pair your proxies with an antidetect browser (e.g. MuLogin, Multilogin). See our Antidetect Browser Setup Guides for tutorials.

6. Switch Target Region #

Some websites apply stricter scrutiny to IPs from certain regions. Jibao Proxy covers 200+ countries and regions — you can freely choose the target country and city when extracting proxies.

7. What to Do When a Static IP Is Blocked #

• Wait for the ban to lift — Some blocks are temporary (typically 24–48 hours)
• Replace with a new IP — Purchase a new static IP from the dashboard
