TLS and CA cert not getting consider for secure connection

[quadnaren]

While connecting to secure Azure managed Redis by setting --tls in redis-cli, it gets connected without error, but the same is not working in the riot command.

1. Confirm the ssl mode and root ca installed
   openssl s_client -showcerts -connect <hostname>:10000

2. Check redis-cli command to confirm the connection (working as expected)
   redis-cli -h <hostname> -p 10000 -a <password> --tls

3. Riot command to test the connection (Not working), but worked by adding --insecure.

./riot ping -h <hostname> -p 10000 -a <password> --tls
Unable to connect to 172.x.x.x/<unresolved>:10000

I tried adding the location by --cacert /etc/ssl/certs/DigiCert_Global_Root_G3.pem, but the result was the same.

4. Disabled the SSL mode on the server side and worked perfectly again!

Is there any issue with picking the CA certificate from the default location, unlike redis-cli?

Can you please check if the VerfiyMode is the issue?
I found the PR that resolved the cluster mode and a few issues with certificate verification redis/lettuce#2837

In this, you can add ARGs to the CLI to configure the mode (CA or FULL). If --insecure provided, then set it to NONE.
