'Authentication error when connecting to redis cluster

I have installed the redis cluster version 6.2.3-alpine on a kubernetes cluster and enabled authentication by setting the following parameters in the config map:

masterauth a-very-complex-password-here
requirepass a-very-complex-password-here

When I try to connect using an AspNet Core application, on the first attempt the following error occurs:

(error) NOAUTH Authentication required

On the next attempt to connect, this error no longer occurs. After the application successfully connects to redis, it runs for about 2 or 3 minutes and then stops communicating, with no apparent error

This behavior happens intermittently and I cannot find a cause for it.

Can anyone help me with this problem?
