We have some people that are at a remote site and unable to access our VPN. They are able to get to the internet, but when they go to the URL to log into the VPN they just get a generic browser error saying "Internet Explorer cannot display the webpage". When we look in our logs, I see the following entry when they attempt to hit the VPN page: PulseSecure: 2016-04-28 21:26:34 - ive - [XXX.XXX.XXX.XXX] System() - SSL negotiation failed while client at source IP 'XXX.XXX.XXX.XXX' was trying to connect to 'XXX.XXX.XXX.XXX'. Reason: 'unknown protocol' (The IPs were intentionally X'd out). Our allowed SSL and TLS Version setting is "Accept only TLS 1.1 and later". I did confirm that in the Internet Explorer Internet Options that they have Use SSL 3.0, TLS 1.0, TLS 1.1, and TLS 1.2 selected in the Advanced settings. The issue is limited only to people at a specific remote site. Everyone else seems to be able to access the VPN just fine. We also had the people having issues try 2 of our other SSL VPN appliances and they are having exactly the same issue. All of the SSL VPNs are configured the same way. Would anyone have a clue what might be causing this error? Our PulseSecure System Info: Model: SA-4500 Current Version: 8.1R6 (build 39491) Thank you!
