Do you want to connect to mongoS?
Is it running?
if not, you should start it using command below
mongos --configdb rsconfig/192.168.123.456:20001,192.168.123.456:20002,192.168.123.456:20003 --port 10001 --fork --logpath /log/mongos_10001.log --bind_ip_all
Which’s format is
mongos --configdb <config-replica-set-name>/<list-of-config-servers> --port <mongos-port> <other-options>
If it’s running, you can connect using the same method as you used to connect to the data servers.
mongo or mongosh either, I can’t get your version cleary
referring manual
also It’s better to attach full log of base situation with text rather than screenshots
have a good day
