Identity Service issue while Oauth setup

Hi all,

I was following this documenation  and this video for setting up the oauth integration.

While doing changes in the appsettings.json, and testing it. I got an error "It was not possible to connect to the redis server(s). UnableToConnect on tscore-dev-30:6379/Interactive, Initializing". In that file, "RedisConnection": "tscore-dev-30" is already set by default.

I also tried to update it with the redis connectionstring which was used in the main application but it is giving me an error while setting up the default response in creatio.

Please help in this regard.
