Upstash Redis AUTH failed while reconnecting using php8.1-redis

Questions / Help
1

After running the upstash redis queue for a while I begin to see connection errors. Here is an example from the command line.

I also see errors in the logs after scheduled jobs have been executed including SELECT failed while reconnecting, and read error on connection to tcp://fly-cold-frog-4960.upstash.io:6379","code":0

Looking for debugging help, or a better redis driver for Laravel.

Thanks!

I assume it is using phpredis. Seems like the choice is generally between that and predis. I see this open issue :thinking:

If it’s that, there’s a suggestion from michael-grunder in there?

Moving from phpredis to predis has solved this issue. Install predis into a Laravel app with composer require predis/predis.

NOTE!:::

If you are going to use upstash for your cache driver as well (like I do), note that upstash doesn’t support database “1”, you must set your REDIS_CACHE_DB = "0" as the default is “1”. You will see SELECT failed: ERR Only 0th database is supported! Selected DB: 1 in your logs if this is set incorrectly.
