Redis://<no master available>/0

Tags: #<Tag:0x00007f0661a3b218>

i’m receiving this error in the log file and it’s working on production server
but not working on my Alpha both server are running on the elasticache.
the alpha and production have different endpoints

<(null)> - Using job storage: ‘redis:///0’
connection string is not injected into the jobstorage
is there any reason why it’s not connected into job storage?
and why it says no master available?

Thanks In Advance!

This is solve.
the fix was right connection string and redis server.
