Troubleshooting AI connectivity

  • Last updated: May 15, 2026

To use Burp AI, your network must allow outbound HTTPS traffic to ai.portswigger.net on port 443.

If your organization uses a firewall or content filtering tool, make sure ai.portswigger.net is allowlisted. You may need to ask a network administrator to do this.

Common connectivity problems

If you can't see your AI credits or use Burp's AI features, the cause is likely to be one of the following:

  • You're offline.

  • Your network requires an upstream proxy.

  • An intercepting proxy is intercepting and re-signing traffic with its own certificate. Burp doesn't trust self-signed certificates by default, so it blocks the connection.

This page provides a step-by-step guide to help you troubleshoot common connectivity problems.

Step 1: Check your internet connection

Make sure your computer is online and able to access PortSwigger's AI services. To do this:

  1. Open a browser and visit https://portswigger.net to confirm general internet access.

  2. Try visiting https://ai.portswigger.net. You should see a 404 Not Found message - this is expected and confirms that your network can reach Burp's AI platform.

If either step fails, check your network settings or contact your administrator.

Step 2: Configure an upstream proxy

Some networks require an upstream proxy to access the internet. If this applies to your environment:

  1. In Burp, click Settings. The Settings dialog opens.

  2. Go to Network > Connections.

  3. Under Upstream proxy servers, click Add. The Add upstream proxy rule dialog opens.

  4. Enter the required proxy details. For more information, see Connections settings - Upstream proxy servers.

  5. Click OK.

  6. The new upstream proxy rule is added to the table.

Step 3: Identify and resolve an intercepting proxy

Some networks use intercepting proxies, such as ZScaler, that decrypt HTTPS traffic and re-sign certificates. Burp doesn't trust these certificates by default, which can block access to AI services.

To check if an intercepting proxy is affecting your connection:

  1. In Burp's browser, go to https://ai.portswigger.net.

  2. In Burp, go to Settings > Network > TLS.

  3. Under Server TLS certificates, find the entry for ai.portswigger.net.

  4. Check the certificate issuer:

    • If the issuer is a well-known CA provider such as Amazon, it's unlikely that an intercepting proxy is interfering with the connection.

    • If the certificate is issued by an intercepting proxy (such as ZScaler), or your company's security system, then your traffic is being intercepted.

If your traffic is being intercepted by a proxy, Burp might not trust the proxy's certificate. This can prevent access to AI features.

To fix this, add the proxy's certificate authority (CA) to Burp's trusted certificates:

  1. Find the path to the proxy's certificate. If you're unsure, check your system settings or ask a network administrator.

  2. In Burp, go to Settings > Network > TLS.

  3. Under Custom CA certificates, click Add.

  4. Select the certificate file.

  5. Restart Burp, then check whether you can access AI features.
