[Solved] Warning: SessionHandler::read(): Redis connection not available

[Buda9]

Hey everyone,

I did a fresh install using git clone and setup from a terminal, and no matter what I did I always receive error 500. So i enabled debug and this is the message I see:

ErrorException: Warning: SessionHandler::read(): Redis connection not available

at /home/user/web/example.com/public_html/vendor/symfony/http-foundation/Session/Storage/Handler/StrictSessionHandler.php:59 at Symfony\Component\HttpFoundation\Session\Storage\Handler\StrictSessionHandler->doRead() (/home/user/web/example.com/public_html/vendor/symfony/http-foundation/Session/Storage/Handler/AbstractSessionHandler.php:99)

My PHP Session Handler is Redis. However, I don't know how to solve this issue in myddleware (and keep Redis as session handler).

I didn't find anything on the internet or this repo that could be of help.

If anyone have any suggestion, please help. Thank you

Solution below

Ok, so after I added some changes to the services and framework (see below), I could see this screen:

myddleware/public_html/config/services.yaml:

services: Redis: class: Redis calls:

• connect:
  • '%env(REDIS_HOST)%'
  • '%env(int:REDIS_PORT)%'

    - auth:

    - '%env(REDIS_PASSWORD)%'

    Symfony\Component\HttpFoundation\Session\Storage\Handler\RedisSessionHandler: arguments:

    • '@Redis'
    • prefix: myd_

myddleware/public_html/config/packages/framework.yaml:

remove handler_id: null add handler_id: Symfony\Component\HttpFoundation\Session\Storage\Handler\RedisSessionHandler

After this, I tried to log in or to install and I saw 404 error.

So I run "php bin/console cache:clear" and I could log in normally. But after that I saw a lot of 404 for assets.

What worked for me is running "php bin/console cache:clear" few more times.

Hopefully this will be useful to someone!

Ps. For reference, I'm using hestia cp, nginx and ubuntu 22
