The server may be down or the URL may have changed. Verify the URL in the connection settings and confirm the server is reachable from outside your network.
Troubleshooting a connection
Run the connection diagnostics from Manage Team > Connections to find out why Fluent cannot reach your Epicor server. The diagnostics run five checks: URL Validation, DNS Resolution, TCP Connectivity, SSL Certificate, and Authentication, and each one shows a pass, warning, or fail with a message.
Run the diagnostics
Go to Manage Team > Connections and open the failing connection.
Click Test Performance. The diagnostics panel runs a set of checks automatically.
Click Run.
Each check reports a result with a message:
URL Validation: the URL is correctly formatted
DNS Resolution: the hostname resolves to an IP address
TCP Connectivity: the server is reachable on the expected port
SSL Certificate: the certificate is valid and not expired
Authentication: the credentials are accepted by the server
Fix the failing check
Match the check that failed to the fix below. After updating credentials or firewall rules, re-run the diagnostics to confirm all checks pass before reprocessing failed documents.
DNS or TCP check fails
SSL Certificate check fails
The certificate may be expired or self-signed. Contact your IT team.
Authentication check fails
The credentials (username, password, or API key) have likely changed. Update them in the connection settings.
Firewall is blocking Fluent
Allowlist Fluent's outbound IP addresses. Email [email protected] for the current IP list.
