This article provides a comprehensive guide to troubleshooting this issue, offering steps to diagnose and resolve the problem effectively. We'll explore potential causes, debugging techniques, and practical solutions to get your Roo Code environment back on track. Let's dive in and tackle this error head-on!

Understanding the Problem

The error message "API Request Failed - X509 to PEM conversion" typically indicates an issue with SSL/TLS certificate handling. This can arise due to several reasons, such as incorrect certificate paths, missing certificates, or problems with the certificate format itself. When Roo Code attempts to make an API request, it needs to establish a secure connection, and if the certificate verification fails, this error is thrown. The X509 to PEM conversion part suggests that the system is having trouble converting the certificate from its X.509 format to the PEM format, which is commonly used for storing cryptographic keys and certificates.

To effectively address this, it's crucial to understand the context in which the error occurs. Is it happening consistently, or only under specific conditions? Knowing when the error appears can provide valuable clues about its root cause. For instance, if it occurs immediately after starting a chat, it might indicate an issue with the initial handshake or authentication process.

Make sure to check your environment variables and configuration files for any certificate-related settings. Look for paths to certificate files or any settings that control SSL/TLS verification. Incorrect configurations can lead to failed conversions and API request errors. Additionally, ensure that the certificates being used are valid and haven't expired. Expired certificates are a common cause of SSL/TLS-related issues. Verifying the certificate's validity period can quickly rule out this potential problem.

Furthermore, consider the network environment in which Roo Code is running. Are there any firewalls or proxies that might be interfering with the SSL/TLS connection? Firewalls can sometimes block certain types of traffic, while proxies can alter the certificate chain, leading to verification failures. Checking your network settings and ensuring that Roo Code has the necessary permissions to communicate securely with the API endpoint is essential for resolving this error. By systematically examining these factors, you can narrow down the potential causes and implement targeted solutions.

Gathering More Details

To effectively troubleshoot the "API Request Failed - X509 to PEM conversion" error in Roo Code, gathering detailed information about the issue is essential. As the user mentioned, finding debug logs can be a game-changer. Start by checking Roo Code's documentation for instructions on enabling debug logging. If specific instructions aren't available, look for general logging configurations that might provide more verbose output. Debug logs can reveal the exact point of failure, the certificates being used, and any error messages from the SSL/TLS library.

In the absence of dedicated Roo Code logs, consider using system-level tools to monitor network traffic. Tools like Wireshark can capture and analyze the SSL/TLS handshake, providing insights into certificate exchange and verification processes. By examining the captured data, you can identify whether the client (Roo Code) and server are negotiating the correct protocols and whether the certificate is being presented correctly. This level of detail can help pinpoint issues with certificate formats or compatibility.

Additionally, it's beneficial to check the logs of the Ollama server, especially if it's responsible for handling SSL/TLS connections. Ollama logs might contain error messages related to certificate validation or conversion failures. Correlating these logs with the Roo Code error can provide a clearer picture of the problem. Look for any entries that indicate issues with certificate paths, permissions, or formats. These logs often contain specific error codes or messages that can be researched further.

If you're using a reverse proxy or load balancer in front of Ollama, examine its logs as well. Reverse proxies often handle SSL/TLS termination, and any issues at this layer can manifest as certificate errors on the client side. Check the proxy logs for any SSL/TLS-related errors, such as failed handshakes or certificate validation failures. These logs can provide valuable clues about whether the problem lies with the proxy configuration or the certificates themselves.

By combining information from various logs and network monitoring tools, you can create a comprehensive view of the SSL/TLS communication process. This detailed perspective is crucial for identifying the root cause of the "API Request Failed - X509 to PEM conversion" error and implementing an effective solution. Remember to correlate the logs with the timestamps of the errors to ensure you're analyzing the relevant data.

Reproduction Steps and Context

The user reports encountering the "API Request Failed - X509 to PEM conversion" error when starting a chat in Roo Code, running on Windows 11 with VS Code. Knowing the specific steps to reproduce the error is crucial for targeted troubleshooting. The user's configuration includes Ollama running locally (localhost / 127.0.0.1) on port 11434. This setup suggests a local development or testing environment, which can simplify the debugging process.

To effectively address the issue, it's important to consider the potential interactions between Roo Code, VS Code, and Ollama. VS Code itself might not directly contribute to the SSL/TLS error, but any extensions or configurations that modify network settings could indirectly impact the connection. Therefore, it's worth checking for any VS Code extensions that might interfere with network requests or certificate handling.

The fact that Ollama is running locally suggests that the SSL/TLS configuration might be self-signed or use a certificate authority (CA) that is not trusted by default. Self-signed certificates are commonly used in development environments but require additional configuration to be trusted by clients. If Roo Code is not configured to trust the self-signed certificate, it will reject the connection and throw the X509 to PEM conversion error.

To resolve this, you need to ensure that Roo Code trusts the CA that signed the Ollama certificate. This can be achieved by adding the CA certificate to the system's trusted root store or by configuring Roo Code to explicitly trust the certificate. The exact steps for configuring trust depend on the operating system and the specific SSL/TLS library being used by Roo Code.

Furthermore, verify that the Ollama server is correctly configured to use SSL/TLS. Check the Ollama configuration files for any settings related to certificate paths, key files, and SSL/TLS protocols. Incorrectly configured SSL/TLS settings can lead to certificate errors and failed connections. Ensure that the certificate and key files are accessible to the Ollama server and that the server is configured to use the correct SSL/TLS protocols.

By understanding the specific context and reproduction steps, you can narrow down the potential causes of the error and focus your troubleshooting efforts on the relevant areas. Pay close attention to certificate trust, SSL/TLS configuration, and potential interactions between the different components of the development environment.

Troubleshooting Steps

  1. Verify Certificate Validity: Ensure the SSL/TLS certificate used by Ollama is valid and not expired. Use tools like openssl to check the certificate's expiration date.
  2. Check Certificate Path: Confirm that Roo Code is using the correct path to the SSL/TLS certificate. Incorrect paths can lead to failed conversions.
  3. Trust the Certificate: If using a self-signed certificate, ensure Roo Code trusts it. This may involve adding the certificate to the system's trusted root store.
  4. Review Ollama Configuration: Check the Ollama server configuration for any SSL/TLS-related settings. Ensure the certificate and key files are correctly specified.
  5. Examine Network Settings: Investigate firewall rules or proxy settings that might interfere with the SSL/TLS connection.
  6. Update Roo Code: Make sure you're running the latest version of Roo Code. Newer versions may have bug fixes related to SSL/TLS handling.
  7. Check System Time: Ensure your system's time and date are accurate, as SSL/TLS relies on correct time for certificate validation.

Variations Tried

The user has not specified any variations tried, indicating that this is the initial attempt to resolve the issue. When troubleshooting, it's helpful to try different approaches to isolate the problem. For example, you could try:
