ping timeout when using go-redis client for pubsub

when using the official redis go-redis client to try and use pubsub I keep getting an error from this line:
https://github.com/redis/go-redis/blob/84706fbcef7646495eecc6bff22f952114459f1c/pubsub.go#L168

the error message takes the following form:
```
redis: 2023/06/01 xx:xx:xx pubsub.go:168: redis discarding bad PubSub connection: redis: ping timeout
```
