Cert and Lets Encrypt Issues

Hi there,

I'm running Carbonio CE v25.6.1

I've ran into issues in trying to get Carbonio to use the Lets Encrypt cert.

I have already requested the cert and it is showing under Virtual Hosts & Certificates.

However, when I request my server, it is still throwing up security errors and when I view the cert, it is showing the self-assigned cert.

Is there anything I should do to get this server to use the letsencrypt cert?

Thanks
