SSL VPN Client Download / User Portal - "Can't connect securely to this page"

Hello Everyone,

I'm rather new to UTM 9, so please forgive what may be a dumb or already answered question. I am attempting to setup a Remote Access SSL VPN on our new UTM 9 instance. I've done this on many Sophos XG115 physical devices with no problems.

I've setup my profiles and users on UTM 9, but when I try to go to http://x.x.x.x:4000. I get "Can't connect securely to this page". This happens on a Windows 10 Pro client running build 16299, through IE 11. I've seen this issue before on a SonicWall, and got around it by accessing the site from a Windows Server 2012 R2, also running IE 11, and with SSL 2.0/3.0 enabled.

Given, that Edge, Chrome, and Mozilla no longer support the RC4 cipher, I know that the answer is something with the Sophos, and not simply the browser.

I would appreciate any hints or guidance.

Thank you,

Luke

  • Hi Luke and welcome to the UTM Community!

    Sorry, you lost me.  What does port 4000 have to do with this?  Are you connecting via SSL VPN before trying to go to http://x.x.x.x:4000?  what is http://x.x.x.x:4000?

    Cheers - Bob

  • I believe that you have not purchased a commercial certificate for your UTM, so the browser does not trust the self-signex certificate offered by UTM.

    In the past, browsers have a issued warning but let you proceed anyway.  With ie11 JI believe Microsoft took away the option of making a mistake.

    Certiificate verification provez server identity, and prevents impostors.  May not matter for UTM, but it matters a lot if you think you are accessing your bank accounts.
