Using a AWS Redis Cluster with 3 nodes. Any idea where to start to debug?

Hi @Nowi5, thanks for writing in about this issue. This would almost certainly be an issue with Predis and AWS not being compatible with each other. This package just provides a functional layer on top of Laravel's caching mechanism. I would file a bug with Predis with a complete StackTrace and go from there. Please do keep me informed of your developments, in case I need to make any updates here. Best of luck!

I have the same issues when using my local docker including redis. Let see if the Laravel Community can help: https://github.com/laravel/framework/issues/33733

[mikebronner]

@Nowi5 Awesome, looks like you got all bases covered. I subscribed to your two other tickets and will follow along to see what comes of it. :)

[Nowi5]

@mikebronner Thank you for your support as always. Found a temporary solution back from 2017. Do you have any deeper insights to judge if that change makes actually sense? Thank you for your expert opinion.

[mikebronner]

@Nowi5 My recommendation would be to switch to PHPREDIS, as that is the recommended path forward by Laravel, I believe.

[mikebronner]

I'm going to work on a release that removes the predis dependency.

[mikebronner]

@Nowi5 Please give release 0.10.0 a try with PHPRedis and let me know how it goes.
