# Troubleshooting

## reCAPTCHA errors

This guide helps you quickly resolve reCAPTCHA verification issues during registration.

When [registering](https://admin.pubnub.com/#/register) for a PubNub's account in the Admin Portal, you may encounter issues related to [Google Enterprise reCAPTCHA](https://cloud.google.com/recaptcha/docs).

![Admin Portal sign-up page showing a reCAPTCHA verification challenge](https://www.pubnub.com/assets/images/recaptcha-errors-f2782362a113ca01368515e88648838e.png)

PubNub uses Google Enterprise reCAPTCHA to keep registration secure. It may show a verification challenge (image or checkbox) or block the action if it detects suspicious patterns.

### Root causes

These errors are not always explicit. They may appear as failed verification or blocked registration.

:::tip Quick check
Before retrying, disable extensions and try a different network. This often resolves verification on the next attempt.
:::

Common triggers include:

| Category | Potential triggers |
| --- | --- |
| Automated browsing or bot-like behavior | Browser automation tools (for example, Selenium, Puppeteer), Many rapid registration attempts from the same IP, Extensions that spoof behavior or modify traffic |
| Suspicious network conditions | Shared or VPN IPs with prior suspicious activity, Data center or anonymizing proxies, Mismatched geolocation or browser metadata |
| Browser or device anomalies | Disabled cookies or local storage, JavaScript errors or script‑blocking extensions, Headless browsers or unusual fingerprints |
| Google account reputation | Signed out of Google or low‑reputation accounts, Incognito/Private mode with lower trust scores |

### Reduce reCAPTCHA errors

To reduce the chance of reCAPTCHA errors:

* Use a standard browser (Chrome, Firefox, Safari, Edge) with JavaScript and cookies enabled.
* Avoid VPNs, proxies, and automated tools during registration.
* Disable extensions that modify page behavior.
* Try a different network if your IP may have abusive traffic.

These steps improve verification success and speed up registration.

If you still cannot complete registration, contact [PubNub Support](https://support.pubnub.com/hc/en-us) and include the time of your attempt and the email used during registration.
