SSL Certificate hostname mismatch - uses IP instead

I'm not sure if this is a FlashFXP bug...

Running vsFTPd as a server on Ubuntu 20.04.

vsFTPd is configured with a certificate which has been issued by my CA.

In FlashFXP, it connects over SSL OK, but I always have a warning when I click on the certificate that the commo name on the certificate doesn't match the server name.

Common name is correct, it's the hostname.
But for some reason, FlashFXP is reporting the server name to be the IP address instead of the hostname.

I can't see why this is. I'm accessing the server by its hostname which is in DNS. I've been throught vsFPTd's config and cannot see anything obvious nor any useful hits when searching online.

Any ideas?

It turns out the certificate was not quite correct.
I've had a new certificate issued and the problem has been resolved.
