nextcloud breaks with redis upgrade 5 to 6

[fredericrous]

I was seeing the following error in the logging pane of nextcloud. I was using version 19 (tag "19", the latest one)

RedisException: ERR AUTH <password> called without any password configured for the default user. Are you sure your configuration is correct? in /var/www/html/lib/private/RedisFactory.php:94

Then I saw this bug report where people were having a similar issue:
https://help.nextcloud.com/t/solved-latest-docker-image-broke-the-installation-redis-password-auth/87598/18

I thought the following PR was the fix but it isn't: #1232

I thought that upgrading to version "20" would solve the issue because the fix was definitely not in image "19". Nextcloud wouldn't boot anymore like it is for the people reporting the issue I just linked. Full stack trace bellow

Adding a password to redis was not a solution for me because other images use the same redis and these images cannot be configured to authenticate with redis. I downgraded to version 5 of redis and nextcloud is now up and running again.

I am not sure but believe the issue I'm having is similar to #1404

I thought the following PR was the fix but it isn't: #1232

Is your Redis password empty or still set to false?

[fredericrous]

Heuu.. Neither? It's just not set. Let me share my docker configs

nexcloud config (without the traefik labels and volume mounts):

  nextcloud:
    image: nextcloud:20
    environment:
      - TZ=${TIMEZONE}
      - MYSQL_HOST=mysql
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_PASSWORD=somepassword
      - REDIS_HOST=redis
      - REDIS_HOST_PORT=6379
      - SMTP_HOST=smtp
      - SMTP_PORT=25
      - MAIL_FROM_ADDRESS=nextcloud
      - MAIL_DOMAIN=${DOMAIN}
      - OVERWRITEHOST=drive.${DOMAIN}
      - OVERWRITEPROTOCOL=https
      - NC_loglevel=1
    networks:
      - traefik_public

redis config:

  redis:
    image: redis:5-alpine
    environment:
      - REDIS_REPLICATION_MODE=master
    networks:
      - traefik_public

if instead of redis:5-alpine I use redis, nextcloud won't start

[J0WI]

Have you checked your config.php?

[fredericrous]

I haven't edited config.php. The password for redis is set to false there

  'redis' =>
  array (
    'host' => 'redis',
    'password' => false,
    'port' => 6379,
  ),

So basically I have to replace false by '' in config.php or declare an empty variable REDIS_HOST_PASSWORD ?

[fredericrous]

It works when I replace false by '' in config.php, thank you J0wi

I think the current documentation of the readme is misleading
REDIS_HOST_PASSWORD (not set by default) Redis password
That's not exactly true, because I had to set redis password to empty, but maybe that's because I was upgrading?

[fredericrous]

I am now getting a 303 error and am stuck on the login page when using redis 6.
I carefully destroyed the containers, removed the cache of redis, changed the config to get 'password' => '', also set REDIS_HOST_PASSWORD= in the compose file, deployed the containers. I cleared my browser's cache. Tried to login and got the 303 error in the logs, no other message, no loop, the URL in my browser address bar is stuck on something like /login?redirect=/apps/dashboard/
I am not getting any issue with redis 5 so I downgraded for now and will give a try to redis 6 when I'll upgrade to nextcloud 21.

Have you tested with nc 21 already?

[pnbecker]

I have the same problem with NC 21.

[JuniorJPDJ]

I managed to workaround it on my side.
Problem is already fixed in #1232 but...
config files seems not to be updated in place
Remove config files from your volume and copy new configs from this repo - this fixed issue for me, I'm now running nextcloud 20 with redis:alpine without password and it works ;)

[mschoettle]

Remove config files from your volume and copy new configs from this repo

Which config files are you exactly referring to?

Those from nextcloud volume.
Container update seem not to update them.
