Hello,

I reported this bug
https://jira.mongodb.org/browse/MONGOSH-355
some time ago.

You seem to have very similar problems with mongodump. It is not going to run, and I tried every single combination of command line possible with a 4096 bit RSA certificate or SSL enabled.
A similar cryptic error message
Failed: can't create session: could not connect to server: server selection error: server selection timeout, current topology: { Type: Single, Servers: [

{ Addr: 127.0.0.1:27017, Type: Unknown, State: Connected, Average RTT: 0, Last error: connection() : EOF }

, ] }
in this case EOF of connection is used here.
All connections, whether local or remote from python work with certificates and TLS enabled.
Only if I remove all TLS from mongod.conf mongodump can connect and do its work

Please do not ask for a specific command line, as said I tried all combinations you simply do not get a proper connect with TLS 1.3

net:
tls:
mode: requireTLS
disabledProtocols: TLS1_0,TLS1_1,TLS1_2
certificateKeyFile: /etc/ssl/certs/mongo.pem

Only if this is removed it works. Even if you add allowConnectionsWithoutCertificates: true it does not work.

The above configuration is used in productive use without any issues for mongod (local and remote through pymongo)
