Errors with an on-premise connection (with .Net Core 3.1 on Docker)-CodePudding

I currently run a .Net Core 3.1 application on Docker (with Nginx as reverse proxy), on an EC2 instance.
I've got an on-premise database (and a VPN tunnel between my VPC and my on-premise router) but when I try to connect to the database, I've got an error and I can't find where it come from and how to fix it.
Here is the stack trace :

CodePudding user response：
Looks like the issue is that both Client (Container) and the SQL Server are talking in different language, i.e. TLS 1.2 or TLS1.3 and either of these is not supported by the SQL Server you are trying to connect. Check the version of SQL Server and patch it has to determine the TLS and SSL ciphers supported by it.
