Description
Hello!
We are using StackExchange.Redis version 2.6.70 in a .NET Core 6.0 project, to connect to a Google Cloud Platform Redis instance (version 5.0.0)(a.k.a Memorystore).
We face issues when we are trying to connect to our instance using the library, while with redis-cli the connection succeeds and we are able to see the contents.
The exception that we get in the code is:
exceptionIt was not possible to connect to the redis server(s). There was an authentication failure; check that passwords (or client certificates) are configured correctly: (OpenSslCryptographicException) error:2006D002:BIO routines:BIO_new_file:system lib
P.S: If we disable authentication and TLS in GCP for our Redis instance, the connection through the library succeeds.

Research direction
Reproduce the connection using StackExchange.Redis 2.6.70 in .NET Core 6.0 against Google Memorystore with authentication and TLS enabled, then compare it with the successful redis-cli connection. Investigate the CA certificate and authentication configuration associated with the BIO_new_file error; done means the library connects successfully while both authentication and TLS remain enabled.
