Initial Checks and Common Causes
When faced with the "Cannot connect to salesforce-api-context" error, starting with a systematic approach is key. Begin by checking the most common culprits, as these often lead to quick resolutions. Thoroughly examining these aspects can save time and effort in the long run.
Verifying Endpoint Configuration
Double-check the endpoint URL and path in your application settings. Ensure there are no typos and that the URL points to the correct Salesforce instance (sandbox or production). In the provided configuration, the URL https://api.salesforce.com/platform/mcp/v1-beta.2/sandbox/salesforce-api-context should be meticulously reviewed. Pay close attention to the sandbox designation, as this should match the environment you are targeting. Any deviation from the correct URL structure can result in connection failures. The command-line snippet provided, npx -y mcp-remote@0.1.18 https://api.salesforce.com/platform/mcp/v1-beta.2/sandbox/salesforce-api-context 8080 --static-oauth-client-info {"client_id":"CONSUMER_KEY","client_secret":""}, must also be verified for accuracy.
Examining Network Environment
Network connectivity is a frequent cause of API connection issues. If you are on a corporate network, there may be proxy servers or firewall restrictions in place that prevent your application from reaching the Salesforce servers. Confirm whether a corporate proxy or egress filtering is in effect, and if so, ensure that your application is configured to use the proxy. Additionally, if a VPN is in use, verify that it is correctly configured and not interfering with the connection. If mTLS (mutual Transport Layer Security) or custom CA (Certificate Authority) certificates are involved, ensure that they are properly installed and configured on your system.
Authentication and OAuth
Authentication problems are another common source of connection errors. Ensure that your application is using the correct OAuth scopes and that the client ID and secret are valid. The provided OAuth scopes (api, refresh_token, offline_access, sfap_api, einstein_gpt_api) should be appropriate for the operations your application is performing. Verify that you are using an External Client App rather than a Connected App, as the latter may not be suitable for all integration scenarios. Also, confirm that the token was issued for the correct environment (e.g., login vs. test domain). Misconfigurations in these areas can lead to authentication failures and prevent your application from connecting to Salesforce.
Common Causes Checklist
Before proceeding with more advanced troubleshooting steps, review the following checklist to rule out common causes:
- Incorrect Audience/Resource/Scope Parameters: Ensure that the audience, resource, and scope parameters in your OAuth requests are correctly configured.
- Using a Connected App Instead of External Client App: Verify that you are using the appropriate type of app for your integration scenario.
- Token Issued for Wrong Environment: Confirm that the OAuth token was issued for the correct Salesforce environment (e.g., sandbox vs. production).
- Proxy Stripping Auth Headers: Check if your proxy server is stripping authorization headers, which can prevent your application from authenticating with Salesforce.
- mTLS Handshake Failures: If using mTLS, ensure that the certificate chain and hostnames are correctly configured to avoid handshake failures.
- Mis-typed Server URL or Path: Double-check the server URL and path for any typos or errors.
Advanced Troubleshooting Steps
If the initial checks do not resolve the issue, it's time to delve into more advanced troubleshooting steps. These steps involve deeper analysis of your application's configuration and network environment. These advanced measures are crucial for identifying less obvious causes of connection failures.
Analyzing Error Messages
The error messages provided in the original report are valuable clues. The message "Error POSTing to endpoint (HTTP 404): "error"}" indicates that the server is not recognizing the requested endpoint. This could be due to an incorrect URL, a missing server definition, or a routing issue. The message "Recursively reconnecting for reason: falling-back-to-alternate-transport" suggests that the application is attempting to use an alternative transport method to establish the connection, which may indicate an underlying network problem. Careful analysis of these messages can provide insights into the root cause of the issue.
Debugging Network Connectivity
Use network diagnostic tools like ping, traceroute, and curl to test connectivity to the Salesforce API endpoints. These tools can help identify network-related issues such as DNS resolution problems, firewall restrictions, or routing errors. For example, ping api.salesforce.com can verify basic connectivity, while traceroute api.salesforce.com can help identify the network path and any potential bottlenecks. Additionally, use curl to send a test request to the Salesforce API endpoint and examine the response headers for any errors. These network diagnostics are essential for ensuring that your application can reach the Salesforce servers.
Examining Logs and Monitoring
Review application logs and Salesforce monitoring tools for additional error messages or warnings. Salesforce provides monitoring tools that can help identify server-side issues or rate-limiting problems. Application logs can provide valuable context about the sequence of events leading up to the error, helping you pinpoint the exact cause. Detailed logging and monitoring are crucial for identifying transient issues or performance bottlenecks that may be affecting your application's ability to connect to Salesforce.
Testing with Different Endpoints
The report mentions that connecting to other servers resulted in mixed outcomes. While platform/sobject-all worked, sobject-mutations returned the same error. This suggests that the issue may be specific to certain endpoints or resources. Testing with a variety of endpoints can help isolate the problem and determine whether it is related to a particular Salesforce service or API. If certain endpoints consistently fail while others succeed, it may indicate a misconfiguration or permission issue related to those specific resources.
