specify protocol olsoctcp in IBM.EntityFrameworkCore

I am trying to define the protocol required to connect to my Informix database using IBM.EntityFrameworkCore. It looks like there is no option to introduce the protocol in the connectionstring.

My command looks like:

scaffold-dbcontext "server=sample.com:9089;databse=dbName;uid=user;pwd=password" IBM.EntityFrameworkCore

When I run the mention command returns this error:

IBM.Data.DB2.Core.DB2Exception (0x80004005): ERROR [08001] [IBM] SQL30081N  A communication error has been detected. Communication protocol being used: "TCP/IP".  Communication API being used: "SOCKETS".  Location where the error was detected: "server ip".  Communication function detecting the error: "recv".  Protocol specific error code(s): "*", "*", "0".

Update I finally got in touch with the IT team and turns out that they are rejecting the connection.

I realy appreciate the effort on resolving my Issue
