RedisException: socket error on read socket when Publish a post (Wordpress SEO enabled)

[abdusfauzi]

Whenever I want to publish a post, the error socket error on read socket present itself. Screenshot below is the error (with Query Monitor enabled).

I wonder if this is Yoast SEO bug, or something else.

Description

I want to publish a post. When I clicked the "Publish" button, the page produce an error socket error on read socket. The error log is as below:

2024/03/07 15:34:55 [error] 5942#5942: *967964 FastCGI sent in stderr: "PHP message: RedisException: socket error on read socket in /home/website/web/app/object-cache.php:1830

Expected Behavior

I expect the post will save, publish and back to the editing page.

Actual Behavior

Halted by error socket error on read socket and the post did not redirect back to the editing page.

Possible Fix

Not sure. I have tried to implement all suggestion installation configuration, including the redis.conf lazyfree-lazy-user-flush as yes as suggest here https://github.com/rhubarbgroup/redis-cache/pull/490#issuecomment-1795948671

Steps to Reproduce

1. Edit or Create new Posts
2. Save as Draft
3. Press "Publish"
