When updating plugins, the site was off

Hi!

This morning, I went to update some plugins, including Woocommerce, and it always updates quickly and completes without errors.

Today, it got stuck…. and when I tried to open another page, it was stuck for several minutes on the page under maintenance.

After analyzing the logs, I saw that the error occurred in redis, which was the one who crashed the site, see the log:

[20-Dec-2022 08:02:26 UTC] Predis\Protocol\ProtocolException: Unknown response prefix: 'a'. [tcp://127.0.0.1:6379] in /home/bhlfitne/public_html/wp-content/plugins/redis-cache/dependencies/predis/predis/src/Connection/AbstractConnection.php:144

I was worried to update other sites.

Could you check what happened or if you need an update?

(I made a github donation for you).

Thanks.
