CUIC Data Source Creation Error - Invalid Sub-Protocol Invalid Sub-Protocol 'sqlserver

[Sathiya Kumar]

We are trying to create a new Data Source connection(SQL Server) in UCCX CUIC 11.6. We are able to connect the DB server is SQL Server Management Studio but while creating a new Data Source using the same SQL Credentials in CUIC, we are facing an error saying "Invalid Sub-Protocol Invalid Sub-Protocol 'sqlserver'". Could any one help me to fix this issue?

Let me know if any additional information is required.

Check TLS.

CUIC is a bit behind the latest security standards and requires lower versions than TLS 1.2. If your server is configured to only allow TLS 1.2 then CUIC may not be able to connect. Wireshark (or Windows Network Monitor) will make this totally obvious.
