Solution

With this situation, the TCPT (or CLC2S or STRATIS) web site is up and operational, however the computer's browser is unable to establish a secure connection to the server. There are two recommended solutions to solving this issue, with either being appropriate based on local computing requirements and directives.

The first option is to use Google Chrome as a browser, which may be downloaded and installed directly from Google's web site. This browser does not have the issue with the certificate configuration that IE or Edge may encounter from time to time.

The second option is to update and adjust the local certificates on the workstation to fix the connectivity issue. Start by going to the following link and running the 2 tools listed below.  Most users have seen an improvement after installation. For each application, follow the sequence of steps and prompts encountered to complete the certificate installation.
