does not seem to work on the following configuration

[ubreddy]

REdis server version: 3.2.7 client connection parameters port: 6380 options: { password: ***, tls: {servername: redisurl}} This redis server hosted on Azure as Redis Cache.... whereas it works on the local client.... version 3.0.5 env = dev works env = prod (where it connects to hosted redis server ) does not work. No error printed on console. Other Redis commands like set, get work fine though... ( not a problem of server availability...)
