You need to use a browser that supports the latest security protocols.
Any browser set up to use MiamiSSL and using at least version 2.1 of MiamiSSL
will work. If you are using Miami (as opposed to MiamiDx) you may need to set
the MIAMI/SSLVERSION3 environment variable to "y", as described in
MiamiSSL.guide.
The SSL security in Voyager 2 is too old and will not work with the Customer Desk,
but Vpoyager 3 works fine. However, Voyager 3 users will need to follow the
non-JavaScript link, even if JavaScript is enabled in Voyager.
