Are you tired of banging your head against the wall, trying to figure out why your Cognito User Pool SAML Federation is throwing the dreaded “Unable to contact the configured provider” error? Well, you’re in luck! In this article, we’ll embark on a journey to solve this puzzle and get your SAML Federation up and running in no time.
Understanding SAML Federation in Cognito User Pools
Before we dive into the troubleshooting process, let’s take a step back and understand the basics of SAML Federation in Cognito User Pools. SAML (Security Assertion Markup Language) is an XML-based standard for exchanging authentication and authorization data between systems. In the context of Cognito User Pools, SAML Federation allows you to authenticate users with an external identity provider (IdP) and then grant access to your application.
Cognito User Pools provide a built-in SAML Federation feature that enables you to configure an external IdP, such as Okta, OneLogin, or Active Directory Federation Services (ADFS), to authenticate users. Once configured, Cognito will redirect users to the external IdP for authentication, and then exchange the authentication response with the IdP to verify the user’s identity.
The “Unable to Contact the Configured Provider” Error
Now, let’s get to the main event – the “Unable to contact the configured provider” error. This error usually occurs when Cognito is unable to establish a connection with the external IdP, preventing the authentication flow from completing successfully.
There are several reasons why this error might occur, including:
- Incorrect or misconfigured IdP settings in Cognito
- Firewall or network issues preventing communication between Cognito and the IdP
- IdP certificate or encryption issues
- Invalid or expired IdP metadata
Troubleshooting Steps
Now that we’ve covered the basics, let’s go through a step-by-step troubleshooting process to resolve the “Unable to contact the configured provider” error.
Step 1: Verify IdP Settings in Cognito
First, ensure that you’ve correctly configured the IdP settings in Cognito. Double-check that the following settings are accurate:
- IdP issuer URL
- IdP certificate fingerprint
- SAML assertion consumer service (ACS) URL
- SAML single sign-on (SSO) URL
You can find these settings in the Cognito console under Federated Identities > SAML IdP > Edit. Make sure to update any incorrect or outdated settings.
Step 2: Check Firewall and Network Connectivity
Next, verify that there are no firewall or network issues preventing Cognito from communicating with the IdP. Check the following:
- Firewall rules: Ensure that the necessary ports are open to allow communication between Cognito and the IdP.
- Network connectivity: Verify that Cognito can reach the IdP’s SAML endpoint.
You can use tools like telnet or cURL to test the connection to the IdP’s SAML endpoint.
Step 3: Validate IdP Certificate and Encryption
Now, let’s investigate possible certificate and encryption issues. Ensure that:
- The IdP’s certificate is valid and not expired.
- The certificate fingerprint in Cognito matches the one provided by the IdP.
- The encryption algorithm and key size are compatible between Cognito and the IdP.
You can use tools like OpenSSL to validate the IdP’s certificate and encryption settings.
Step 4: Update IdP Metadata
If you’ve recently updated the IdP’s certificate or encryption settings, ensure that the metadata reflects these changes. Update the IdP metadata in Cognito to reflect the latest changes.
Step 5: Test the SAML Flow
Finally, test the SAML flow to verify that Cognito can successfully communicate with the IdP. You can use the Cognito console or a tool like Postman to test the SAML flow.
Here’s an example of a SAML request:
<?xml version="1.0" encoding="UTF-8"?> <samlp:AuthnRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol" ID="_1234567890abcdef" Version="2.0" IssueInstant="2023-02-20T14:30:00Z" AssertionConsumerServiceURL="https://your-cognito-domain.auth.us-east-1.amazoncognito.com/saml2/idpresponse" > <saml:Issuer xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion">https://your-idp-domain.com</saml:Issuer> </samlp:AuthnRequest>
If you’re still encountering issues, check the Cognito logs for more detailed error messages. You can also use tools like SAML tracers or debuggers to inspect the SAML flow and identify the issue.
Conclusion
In this article, we’ve explored the world of Cognito User Pool SAML Federation and troubleshooting the “Unable to contact the configured provider” error. By following the steps outlined above, you should be able to identify and resolve the issue, getting your SAML Federation up and running in no time.
Remember to double-check your IdP settings, firewall and network connectivity, IdP certificate and encryption, and IdP metadata. If you’re still stuck, feel free to reach out to AWS support or the Cognito community for further assistance.

Frequently Asked Question
Are you tired of encountering the “Unable to contact the configured provider” error while setting up Cognito User Pool SAML Federation? Don’t worry, we’ve got you covered! Here are some frequently asked questions and answers to help you troubleshoot and resolve the issue:
Q1: What are the common causes of the “Unable to contact the configured provider” error?
This error can occur due to a variety of reasons, including incorrect IdP metadata, misconfigured SAML provider, network connectivity issues, or outdated certificate expiration dates. It’s essential to review your setup and identify the root cause of the problem.
Q2: How do I troubleshoot the issue with my IdP metadata?
To troubleshoot the issue, review your IdP metadata file and ensure it’s correctly formatted and contain the required attributes. You can also use online tools to validate your metadata file. Additionally, try importing the metadata file into your Cognito User Pool again to see if the issue persists.
Q3: What should I do if my SAML provider is misconfigured?
Double-check your SAML provider’s configuration and ensure it matches the requirements specified in the AWS documentation. Verify the Entity ID, Assertion Consumer Service (ACS) URL, and Single Logout (SLO) URL are correct. You may need to consult with your IdP administrator or SAML provider’s documentation for assistance.
Q4: How can I resolve network connectivity issues affecting my Cognito User Pool?
Check your network configuration and ensure there are no firewall rules or proxy servers blocking the connection between your application and the IdP. You can also try testing the connection using tools like curl or Postman to identify any issues.
Q5: What should I do if my certificate is expired or outdated?
Renew or update your certificate to ensure it’s valid and not expired. You may need to obtain a new certificate from your IdP or Certificate Authority. Once you have the updated certificate, update your Cognito User Pool settings with the new certificate.
