DQE connectivity issues in Salesforce can occur when the Salesforce environment cannot reach the expected DQE service, when authentication is not valid, or when environment-specific configuration does not match the integration setup.
Common symptoms
- DQE validations fail with a connectivity or authentication error;
- the issue affects one Salesforce environment but not another;
- requests fail after a sandbox refresh or deployment;
- the integration works for some users or objects but not others;
- timeouts or unexpected API errors are returned.
What to check first
- Confirm that the correct DQE endpoint and environment are configured.
- Verify that credentials, licence information, or tokens are still valid.
- Review any recent Salesforce configuration, package, or network changes.
- Check whether access restrictions, proxy settings, or IP filtering may apply.
- Compare the configuration with an environment where the integration works.
Authentication and access
Connectivity issues are often linked to environment-specific configuration. Make sure that the Salesforce environment uses the correct credentials and that any access restrictions required by the DQE service are still valid.
When to contact DQE Support
If the issue persists, provide the Salesforce environment, DQE service concerned, endpoint, request timestamp, error message, affected users or objects, and any recent deployment, sandbox refresh, or configuration change.
