> The gRPC server TLS setup applies the configured cipher list directly when 
> building the Netty OpenSSL context. If any configured cipher is unsupported 
> (and there is no supported cipher in the list before that), TLS context 
> creation throws an error and SCM startup fails.
> Unsupported ciphers in the configured list should be filtered out and service 
> startup should continue if at least one valid cipher remains.
> Instead of this:
> {code:java}
> sslContextBuilder.ciphers(securityConfig.getGrpcTlsCiphers()); {code}
> It should use Netty SupportedCipherSuiteFilter.INSTANCE when applying 
> configured cipher lists in gRPC server TLS context builders: 
> {code:java}
> sslContextBuilder.ciphers(
>     securityConfig.getGrpcTlsCiphers(),
>     SupportedCipherSuiteFilter.INSTANCE); {code}
