A proxy and a CAPTCHA solver handle different parts of one task. For some challenges they need to use the same exit IP: when that matters, how to set it up, and what to check.
The proxy connects, the website loads and the task starts. Then a CAPTCHA appears and the workflow pauses. A proxy and a CAPTCHA solver handle different parts of that process: Proxy302 provides the network connection, and CaptchaAI handles supported verification challenges. For some challenges the two need to use the same exit IP.
Proxy302 offers rotating residential, static ISP and datacenter proxies. Its rotating residential network covers more than 195 countries and regions.
CaptchaAI is an AI-powered CAPTCHA-solving service. It supports reCAPTCHA v2 and v3, including Enterprise variants, Cloudflare Turnstile, Cloudflare Challenge, GeeTest v3 and more than 27,500 image CAPTCHA formats, and it offers an API, a 2Captcha-compatible Emulator and a Chrome extension. Plans start at US$15 per month.
Every subscription plan includes unlimited solves within the selected thread capacity. Threads set how many tasks run at the same time: five threads support five concurrent solving tasks, and a thread becomes available again when its task finishes. There is no fixed daily or monthly solve quota.
Use this kind of workflow only in environments you own, that a client has authorized, or that a contract permits.
It depends on the challenge and on the website’s verification process. For CaptchaAI’s Cloudflare Challenge method, the solving request and the later website requests must use the same exit IP, and the returned cf_clearance cookie must be used with the User-Agent the solver returns.
For other supported methods, provide a proxy only when the website or the integration requires IP matching. One important exception: CaptchaAI does not support reCAPTCHA v3 solving with a user-supplied proxy. Your browser can use a proxy, but do not pass it to CaptchaAI for the v3 task.
The same proxy host and port does not guarantee the same exit IP when rotation is on. An IP-sensitive workflow needs a connection that stays the same through the whole page-and-solve sequence.
| Item | Value | Note |
|---|---|---|
| Host | proxy.proxy302.com | Rotating residential gateway |
| HTTP port | 2222 | Use with the HTTP protocol |
| SOCKS5 port | 3333 | Use with the SOCKS5 protocol |
Source: Proxy302 product facts, 10 November 2026. For static ISP and datacenter assets, use the details shown on the asset in My assets. When the workflow needs IP consistency, choose a static connection or a sticky session and check that the exit IP stays stable: a sticky session is not a permanently fixed IP.
Copy the host, port, username, password and protocol from your Proxy302 account. Rotating residential uses the gateway in the table above; static ISP and datacenter assets show their own details.
Sign in and open Account Configuration. Set Proxy to Active before you submit a supported task with proxy parameters. The same page has User Agent and Cookies controls: set them according to what the method requires instead of turning every option on.
Configure your HTTP client or browser automation tool to use the Proxy302 connection. Identify the CAPTCHA type and collect the inputs its CaptchaAI method needs: a reCAPTCHA v2 task and a Cloudflare Challenge task do not take the same parameters. Keep the session available while the solving task runs.
For supported methods that need a proxy, include proxy (the address and login) and proxytype (the matching protocol). For username and password authentication the documented format is login:password@HOST:PORT. Follow the Using Proxies documentation together with the page of the CAPTCHA method you use, and match proxytype to the protocol of your Proxy302 connection.
Retrieve the result with the method’s documented polling flow and apply the returned token the way the website expects. For Cloudflare Challenge, use the returned clearance cookie and User-Agent through the same exit IP.
Expected result The expected content loads or the action completes. A returned solution alone does not confirm that the website accepted it.
An authorized collection task reaches a Cloudflare Challenge instead of the expected page. The application pauses that task and submits a Cloudflare Challenge request to CaptchaAI with the required proxy details. When the result is ready, it applies the returned cf_clearance cookie and User-Agent, then requests the page through the same exit IP.
It checks for the expected page content before marking the task complete. If another verification page appears, it records the failure for investigation instead of restarting the same task again and again.
This keeps apart three outcomes that are easy to confuse: the proxy connected, the solver returned a result, and the website accepted the session.
Enter the Proxy302 host, port, username, password and matching protocol. Run a connection check and confirm the exit IP from inside the profile. Setup guides for supported tools are on the Proxy302 partners page.
Where the browser supports Chrome extensions, install the CaptchaAI Chrome extension inside the profile you will use. Enter your API or account key, save the settings and enable the CAPTCHA types the task needs.
Check detection, solving and the final website response. Behavior depends on the CAPTCHA type, the site and the CaptchaAI extension settings, and solving needs available threads or an active subscription.
Before continuing A proxy set in the browser profile does not confirm that the solver uses it. For Cloudflare Challenge workflows that need explicit proxy and cookie handling, follow the API method documentation.
The CaptchaAI Emulator is a compatibility option for tools that use supported third-party CAPTCHA-service integrations. Follow its setup instructions and test the CAPTCHA types your application needs before you move a larger workload. Migration steps vary by tool: changing only the API host and key is not a universal procedure.
| Item | Option to consider | Main check |
|---|---|---|
| Authorized account workflows that need a consistent address | Static ISP | Keep the intended IP and region consistent. |
| Data collection that needs session continuity | Rotating residential with sticky sessions | Verify a stable exit for the page-and-solve sequence. |
| Tasks on sites that accept hosting-network IPs | Datacenter | Test access, response times and how often challenges appear. |

Check Did the exit IP change, did the result expire, or was it applied incorrectly? For Cloudflare Challenge, also check the returned User-Agent.
Fix Keep one exit IP for the page-and-solve sequence and use the returned cookie and User-Agent on every later request.
Stop when If it fails twice with the same inputs, stop and read the returned error instead of submitting new solves.
Check Is Proxy set to Active in Account Configuration, does proxytype match the protocol, and are the credentials free of stray spaces?
Fix Fix the setting, then check that the proxy can reach the target domain.
Check Authentication restrictions and IP allowlisting, if you use them.
Fix Review those settings: local connectivity does not prove that the proxy is reachable from the solver’s environment.
Check Request frequency, concurrency and session continuity.
Fix Compare connection options with a small representative test instead of assuming a different proxy type will fix it.
Check The active thread capacity has been reached.
Fix Queue extra tasks in your application until a thread is free, or increase the thread count.
CaptchaAI gives Proxy302 users a 3-day trial with 50 free threads, including unlimited solves within the trial’s 50-thread capacity. To activate the trial, send the code Proxy302 to @AskCaptchaAI on Telegram.
Use the trial to test the CAPTCHA types you need, the proxy settings and the complete workflow before choosing a subscription. After testing, Proxy302 users can get up to 15% off through CaptchaAI’s special offer for Proxy302 users. All subscription plans include unlimited solves within the selected thread capacity. CaptchaAI sets these terms.
CaptchaAI users get 20% extra balance on a first Proxy302 top-up, up to US$50, by registering through the CaptchaAI partner link. The bonus is credited automatically. A qualifying US$100 first top-up gets US$20 extra, and a US$250 first top-up reaches the US$50 cap.
Start with the connection that suits your workflow and test it with the CAPTCHA method you actually use: connectivity, exit IP consistency and the final website response, before you raise the workload.
No. Pass it when the method needs the solver and your application on the same exit IP, as Cloudflare Challenge does. For reCAPTCHA v3, CaptchaAI does not support a user-supplied proxy.
On proxy.proxy302.com the HTTP port is 2222 and the SOCKS5 port is 3333. Match the proxytype you send to CaptchaAI to the protocol you generated.
No. With rotation on, requests through the same gateway can leave through different IPs. For the page-and-solve sequence use a static IP or a sticky session, and check the exit IP.
Send the code Proxy302 to @AskCaptchaAI on Telegram. The trial gives 50 free threads for 3 days.
No proxy type guarantees that. Request patterns, browser behavior and website rules also affect the outcome, so test your own workflow.
Register through the CaptchaAI partner link. The bonus is 20% extra balance on the first top-up, up to US$50, and is credited automatically.
Three Exit mode options decide whether a residential proxy keeps one IP or changes it; new proxies start on sticky.
Static IP vs dynamic IP: how DHCP assigns addresses, private vs public addresses, when you need a static IP, and what the terms mean in proxies.
The ERR_PROXY_CONNECTION_FAILED error appears in Chrome and Edge when the browser cannot establish a connection with a proxy server.
Every working proxy is described by five basic fields: protocol, host address, port, login, and password.
