CAPTCHA can appear even when a website opens without any errors: the page loads, but before you can continue, it asks you to prove that you are not a robot. Repeated challenges can be especially disruptive for web scraping and browser automation.

There may be several reasons: a high request rate, repetitive actions, browser session characteristics, or the IP address the requests come from. So if CAPTCHA appears regularly, it is worth checking not only the workflow, but also the connection being used.

A proxy routes requests through a different IP address. This can be useful if a website restricts access from certain addresses or if the connection's geolocation matters for the task.

Residential proxies are sometimes used to deal with CAPTCHA. Their IP addresses belong to real internet users and are associated with home internet connections. This type of address may be suitable for tasks where the connection region and IP type matter. However, a residential proxy does not guarantee that CAPTCHA will not appear: the website itself decides whether to require verification.

For example, Node Proxy residential proxies let you choose a geolocation. This helps you select a connection region for your task and check whether the IP address being used affects the appearance of CAPTCHA.

In some scenarios, not only the proxy type matters, but also how long the same IP address is used. If a website frequently displays CAPTCHA after a series of requests, you can check whether using a different address changes the situation.

Node Proxy lets you configure IP address rotation. Depending on your task, you can choose a suitable rotation mode, such as rotation by time or by request. Rotation lets you distribute requests across different addresses, but it does not remove the website's restrictions. If CAPTCHA is caused by an excessively high request rate or repetitive actions, you should also review the workflow itself.

If the proxy does not connect or the website does not open, check the connection first. Make sure the proxy details are entered correctly, then check whether the address is reachable and verify your current IP.

You can use the Node Proxy proxy checker for this. The check can help you determine whether the connection is working before you look for the cause of CAPTCHA in the browser or automation workflow.

If your task requires keeping the same IP address throughout a session, you can also consider Node Proxy static proxies. They are suitable for scenarios where changing the address during a task is undesirable.

Changing the IP address does not always solve the problem. If CAPTCHA keeps appearing, check the request rate, the number of parallel tasks, and the browser session state. Increase the intervals between requests, avoid endless retries, and make sure the workflow follows the website's access rules.

If CAPTCHA still regularly interrupts an authorized automation workflow, you can consider specialized services for handling it, such as CaptchaAI. Such a service can be a separate step in the workflow, but it does not replace properly configuring the proxy and the automation itself.

To deal with CAPTCHA, it is useful to check the connection, IP geolocation, and automation behavior in sequence. Residential proxies can be one option, especially when addresses associated with real users' internet connections matter for the task. Configuring rotation also lets you test how the workflow performs with different IP addresses.

However, a proxy does not guarantee that CAPTCHA will disappear completely. If the challenge appears again, it is important to identify the cause and, if necessary, adjust the request rate, session settings, or workflow itself.
