How to Fix Connection Errors in Make.com

Connection issues in make.com can break your automations at the worst possible time. This step-by-step guide explains how to diagnose and fix connection errors so your scenarios can run reliably again.

Before You Start Troubleshooting Make.com Connections

When a connection error appears in make.com, the platform usually reports it during a scenario run or when you save a module. Before changing anything, capture as much detail as you can.

• Note the exact error message and timestamp.
• Identify which module and connection failed.
• Check if the error appears every run or only sometimes.

This basic information will help you apply the correct fix and, if needed, speed up communication with support teams.

Common Causes of Make.com Connection Errors

Most connection problems in make.com fall into a few repeatable categories. Understanding them helps you pick the right remedy quickly.

• Expired, revoked, or invalid API tokens and passwords.
• Changed permissions, scopes, or access levels.
• Incorrect or outdated connection settings.
• Temporary issues on the third-party service side.
• Network, firewall, or VPN restrictions blocking traffic.

The steps below walk you through each area in a structured way.

Step 1: Verify the Third-Party Service Outside Make.com

First confirm the connected service works independently of make.com. This isolates whether the problem is with the external app or with the connection setup.

1. Log in directly to the external service in your browser.

2. Check that your user account is active and not locked or suspended.

3. Test a simple action (for example, send an email, create a record, or list data).

4. Review the service status page for known outages.

If the app does not work outside make.com, fix that issue first or wait until the service restores normal operation.

Step 2: Review the Error Message in Make.com

The error message in make.com often points directly to the root cause. Pay attention to useful details such as HTTP status codes and permission notes.

• 401 or 403 errors: Usually indicate invalid credentials or insufficient permissions.
• 404 errors: Point to missing resources, wrong URLs, or incorrect IDs.
• 429 errors: Suggest rate limits or throttling on the external service.
• 5xx errors: Typically reflect temporary issues on the provider’s servers.

Use this information to choose between resetting credentials, editing module fields, or simply retrying later.

Step 3: Reset or Recreate the Connection in Make.com

If credentials could be the issue, recreate the connection in make.com to ensure a clean authentication process.

1. Open the scenario and locate the failing module.

2. Click the Connection field and select Add or Reconnect.

3. Follow the authorization flow for the external app (OAuth, API key, token, or username/password).

4. Confirm the requested scopes or permissions match what the module needs.

5. Save the scenario and run it once manually to test.

If the new connection works, you can remove unused or outdated connections to keep your make.com workspace clean and secure.

Step 4: Check Permissions and Scopes for Make.com

Many third-party services use granular scopes or permissions that can block actions from make.com even when authentication succeeds.

1. Review the app’s security or API settings for the connected user or integration.

2. Confirm the token or OAuth app has the correct scopes (for example, read/write, admin, or specific resource access).

3. Adjust roles or scopes if the service allows it, or create a new token with the required access.

4. Update or recreate the connection in make.com using the newly granted permissions.

After updating scopes, test again by running the scenario or the individual module.

Step 5: Validate Module Configuration in Make.com

Even if a connection is valid, incorrect module settings can trigger connection-like errors in make.com. Double-check every important field.

• Confirm the correct connection is selected, especially if you use several accounts.
• Review URLs, endpoints, and IDs for typos or wrong values.
• Inspect any custom HTTP headers or query parameters.
• Ensure mapped fields are present in the source data and not empty when required.

When in doubt, simplify the module configuration temporarily. Remove non-essential filters, extra headers, or advanced options, then test again.

Step 6: Test with a Minimal Scenario in Make.com

Testing a single module in isolation helps identify whether the problem is local to one step or related to your entire scenario in make.com.

1. Create a new blank scenario.

2. Add only the problematic app module.

3. Use the same connection that fails in your original scenario.

4. Enter the smallest valid input needed to run the module.

5. Execute the scenario once and compare the result.

If the minimal scenario works, the issue likely comes from data, filters, or other modules in your original flow.

Step 7: Consider Network and Security Restrictions

Enterprise networks and strict security setups can interfere with communication between make.com and external APIs.

• Check if a VPN, proxy, or firewall blocks outgoing requests from your environment.
• Ask your IT team whether specific IP addresses or domains used by make.com must be allowlisted.
• Verify that your security tools do not strip required headers or modify requests.

When restrictions are in place, document any required IP ranges or domains and coordinate with your network administrators.

Step 8: Gather Logs and Contact Support

If you still cannot resolve the connection error in make.com, prepare a clear summary before reaching out for help.

• Scenario name and affected modules.
• Exact error message and any codes.
• Screenshots showing connection settings and module configuration (without exposing secrets).
• Timestamp of the last failed run.

With this information, you can contact the support team of the external service or the make.com support team. Detailed diagnostics significantly reduce back-and-forth and speed up the resolution.

Best Practices to Avoid Future Make.com Connection Issues

Once your connection works again, apply these long-term practices to minimize future disruptions in make.com.

• Use dedicated integration accounts: Avoid personal accounts that might be disabled or lose access.
• Document token lifetimes: Track expiry dates and refresh or rotate tokens before they lapse.
• Limit and review permissions: Use only the scopes you need, but ensure they cover all actions in your scenarios.
• Monitor scenario history: Check run logs regularly for early signs of intermittent failures.
• Standardize connection naming: Use descriptive names so you can quickly identify which scenarios depend on each connection.
