❓ What to do in case of "Insecure Connection" / Expired SSL Certificate?

This article provides administrators with troubleshooting instructions when browsers report an "Insecure Connection" and explains the necessary steps for requesting and securely transmitting a new SSL certificate to support.

Cause and initial steps

Expired or faulty SSL certificate

The SSL certificate you are using has either expired or is missing important parts of the certificate chain (for example, intermediate certificates or root certificates).

What do I need to do?

1. Request a new certificate: Request a new SSL certificate from your certificate authority.

2. Check the chain: Ensure that the certificate is valid and contains the entire certificate chain.

3. Provide the private key: The private key belonging to the certificate must be available.

The certificate must be in .pfx or .p12 format, as only these formats include the private key.

Submitting the certificate (Cloud vs. OnPremise)

Important note for OnPremise customers: The certificate replacement on an OnPremise installation is performed by you. Please do not create a support ticket for this.

If you are an FTAPI Cloud customer, please create a ticket with FTAPI support to initiate the submission of the new certificate.

Important: Never send the certificate and the password to support unencrypted!

Upon request, support will be happy to create a SubmitBox ticket for you, which you can use for the secure upload of the .pfx file or .p12 file.
