HTTPS Listener not accepting on port 443

Post by ckbourke » Tue Aug 22, 2017 11:26 am

Greetings,

I am running Cerberus FTP version 8.0.12.1. I have an HTTPS listener on port 443 and another on port 8443. My firewall is currently accepting traffic on to both ports. When I try to connect on port 443 the log indicates "Connection is not an SSH 2.0 connection" and fails. It shows Incoming requests as being SSH SFTP requests. When I connect on port 8443 it shows the incoming requests as HTTPS which is as expected. I can't figure out why traffic on 443 does not work as expected. Any assistance would be greatly appreciated.

Excerpt from log:

2017/08/22 11:20:59 [166] Incoming connection request on SSH interface 19 at 192.168.1.216

How are you trying to connect?

While it's possible to use Cerberus to transfer files through HTTPS without the web client, we didn't design the server to be used in that way.

I'm accessing it via different browsers (IE, Firefox) using https://sftp.mycompany.com:443. It does not work with 443 yet it does when I use https://sftp.mycompany.com:8443

It simply looks like your listener for port 443 is not configured correctly.
You will want to ensure that port 443 is configured to use HTTPS.
