Connecting sidekiq to twemproxy(nutcracker)

Question

I'm trying to connect my sidekiq to a twemproxy instead of a direct Redis connection, but I'm getting the following error:

It seems that I'm loosing the connection, but I could not identify what is the root cause. Do you know if it is compatible to try this kind of connection?

Answer 1

The latest version of sidekiq (by the time 2.14.1) is able to connect to twemproxy instead of a redis server.

But due to the use of brpop command, it is not compatible.
