Secure Access Clients Recieve EER_SSL_Protocol_Error

zachartl

Level 1

Hello,

We are receiving reports of some VPN Client users, who will get this error message (screen shot attached). We're not utilizing SSL VPN. We're utilizing the Cisco Secure Client version 5.1.8 

This problem seems to occur when our users are in public spaces, Hotels, Libraries for example. I am unable to find any support threads relating to this issue and so I'm writing you all to see if you've any idea what could be sometimes creating this issue. We're using both MFA (Azure Entra) and Username password. The VPN Device is a Cisco ASA, version 9.18.4(22).

Thank you,

Terry

You use asa or ftd ?

MHM

We're using an ASA as our VPN head-end.

 

Do

Show ssl <<- in asa check ssl verion use 

It can client use different ver than asa

MHM

We use package files to upgrade our VPN client software from the ASA. If you log into our ASA for VPN connection and the ASA detects a client version less than the version we've installed, the ASA will automatically upgrade the VPN client software. All of our clients are at 5.1.8 (Cisco Secure Client).

I am talking about ssl ver not secure client ver.

The error log meaning there is issue in ssl protocol 

MHM

I see, sorry about that.
