Troubleshooting

reCAPTCHA errors

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

When registering for a PubNub's account in the Admin Portal, you may encounter issues related to Google Enterprise reCAPTCHA.

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.

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 and include the time of your attempt and the email used during registration.
