If you are using Portal application Assure Unified Interface you may want to turn off deprecated SSL/TLS protocols.
By default TLSv1.2, TLSv1.1, TLSv1 are enabled.
To do this you will have to modify config files server.xml and/or server.https.xml located in /VISIONSOLUTIONS/HTTP/VSISVR/HTTPSVR/conf/ directory
After this modification portal restart is required.
To check if old protocol is available use this command :
openssl s_client -connect server_name:8410 -tls1_1
