Sophos Connect SSL warning message

This message pops up when I try to connect. We have other people using the same setup without issue. Is there something wrong with my config file? It does connect, but it needs to be secure.

My Config file looks like this:
[
{
"gateway": "REDACTED",
"user_portal_port": 443,
"otp": false,
"auto_connect_host": "10.10.10.1",
"can_save_credentials": true,
"check_remote_availability": false,
"run_logon_script": false
}
]

Hi Weston Gately , Thank you for reaching out to the community, under the global SSL Settings, what is the certificate used ? Use ApplianceCertificate issued by the default CA when configuring SSL VPN…

When using a provisioning file as per the configuration above Sophos Connect will connect to the user portal specified at "GATEWAY" to grab the openvpn configuration file for the user that logs in. The message that you're seeing is related to the certificate used on the user portal and is the same as if you were to access it manually at https://REDACTED:443

By default this is a self signed certificate from the firewall which causes this warning to appear.

Where can I find what the User portal port is set to?

The certificate used for user portal is the same for admin portal, captive portal, spx registration & reply portal

It can be found at Administration > Admin and User Settings > Certificate

So, I see the "ApplianceCertificate" is set. Is this certificate not secure or is it possible that it needs to be re-signed?

The certificate itself is secure, but the place it comes from is not a trusted certificate authority like DigiCert, Google, GoDaddy, etc. This is a self signed certificate generated by the firewall, so you can trust it's origin but your computer will warn you about it as it's not one of the many trusted CAs.

If you want to ultimately get rid of that warning you'll need to purchase a certificate and upload it to the firewall.

Ahh I see. I figured it was self-signed. Despite that, it's not an issue then?

If it was your device that signed the certificate, and you trust your device then no self signed certificates would not be an issue.

So, this certificate is from GoDaddy. That should mean that it is definitely signed by a trusted CA. Or am I missing something?

What certificate?

The SSL VPN certificate is not the certificate used here. The certificate that is causing this warning is the User Portal certificate.

We initially thought the previous IT Manager assigned a certificate that was from GoDaddy but we just found that it's not and it's self-signed. I think we understand what's going on now
