Firepower 1010: Management Web Server Certificate

[7benjamin7]

Trying to implement a SSL cert for the web server on a Firepower 1010.

Not managed by a FMC (yet). Still in Testing/R&D phase.

I'm not using a known/trusted certificate authority. I have my own CA cert, generated locally, distributed locally, then used it to create and sign certificates for use.

I can use the cert for remote access vpn, but keep getting: "An unexpected error occurred." when trying to use it for web management. a self-signed cert works fine, a globally trusted cert also works fine.

Is there a known issue regarding a locally trusted CA and the web management that I'm unaware of?

It will use the object "DefaultWebServerCertificate". You can replace the self-signed version of that object with a CA-signed certificate.

Here is an example from my lab where I am using a certificate signed by my Windows Server 2016 CA:

FDM Certificate
