AccessNow 3.x dropped support for Safari 5.x Websocket. The Safari 5.x Websocket is outdated and no longer supports the current WebSocket standard.
This means that Safari 5.x users can only connect via HTTPS using the ESG.
We can help you setup a VM to run the ESG to handle this subset of users. You will have to add an additional bookmark in Juniper to point to the ESG VM, and this bookmark can be assigned to the older Safari users.
