@kerbong, looks like Redis server still isn’t running. You have to launch it, ensure it is running and listening on localhost port 6379 (these are defaults) before launching either anycable or rails. Redis is essential as all communication between anycable and rails is going through it.

To start Redis on Linux you should execute command like this:

sudo systemctl start redis

and check if it is running like this (it should be on active (running) state):

$ sudo systemctl status redis.service        
● redis.service - Advanced key-value store
     Loaded: loaded (/usr/lib/systemd/system/redis.service; disabled; vendor preset: disabled)
     Active: active (running) since Tue 2021-07-27 15:16:21 MSK; 4min 32s ago
   Main PID: 8832 (redis-server)
     Status: "Ready to accept connections"
      Tasks: 5 (limit: 38350)
     Memory: 4.0M
        CPU: 916ms
     CGroup: /system.slice/redis.service
             └─8832 /usr/bin/redis-server 127.0.0.1:6379

And you can check connectivity with redis-cli tool (should be installed along Redis server, but not sure):

$ redis-cli -h 127.0.0.1 -p 6379     
127.0.0.1:6379>

But if you’re getting following message, then it is not ready to be used yet:

$ redis-cli -h 127.0.0.1 -p 6379            
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected>

If you run Redis and application inside Docker containers then you need to use Docker hostnames in anycable configuration.
