Installing Certificate for the NI Application Web Server

[Mark_Yedinak]

I have an externally signed certificate for TLS that I am trying to install to replace an expired certificate. I have followed the process described here. Everything appears to work but when the application web server is restarted so it will pick up the new certificate I see that the certificate has disappeared. The files are still there but when looking at the application web server info in the ancient Internet Explorer interface the certificate is gone. I have enabled logging for the application web server but I never see any entries in the log file. This had worked in the past but now nothing is working. BTW, the certificate works fine as the NI System Web server uses it and everything works as expected. The certificate is also used on a different linux based web server (it is a wildcard certificate for my domain). I would like to get this certificate installed and working. Anyone have any suggestions?

I should also note that in the race instances that the certificate still appears in the Ni Application Web Server configuration (via the Internet Explorer interface) any attempt to invoke a connection using TLS is rejected immediately. A trace using Wireshark shows the connection is accepted and the Client Hello message is received from the client then the connection is immediately closed with a TCP-RST by the server. All of this had worked properly in the past. The only difference is that I am installing a new certificate since the old one expired. This certificate is valid since it works with the NI Web Server as well as a Linux based Apache server.
