All,
I replaced redis with valkey tonight on a long-running nextcloud
install. I followed the wiki pages exactly:
https://wiki.archlinux.org/title/Valkey
(I set all options as shown to suppress warnings)
and
https://wiki.archlinux.org/title/Nextcloud#Valkey_(Redis)
(valkey is running on unixsockets per the wiki)
However, upon starting/enabling valkey and restarting apache,
attempting to reach nextcloud results in:
<quote>
Internal Server Error
The server encountered an internal error and was unable to complete your
request.
Please contact the server administrator if this error reappears multiple
times, please include the technical details below in your report.
More details can be found in the server log.

git, http and nextcloud were added to the valkey group:
$ grep valkey /etc/group
valkey:x:971:git,http,nextcloud
valkey is up and happily running and the socket has 0770 permissions
per the wiki:

The config.php was updated per the wiki to use valkey:
$ sudo tail /etc/webapps/nextcloud/config/config.php
'filelocking.enabled' => true,
'memcache.distributed' => '\\OC\\Memcache\\Redis',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' =>
array (
'host' => '/run/valkey/valkey.sock',
'port' => 0,
'timeout' => 0.0,
),
);
Attempting to access the nextcloud instance results in 6 messages in
nextcloud.log (they repeat each time nextcloud does its cron update).
I've summarized each in pretty-print so they are readable:

This has me baffled. Both the valkey(redis) and nextcloud wiki
changes make logical sense and seem like that should result in a
painless upgrade. I was not so lucky.
Is there something else needed to switch nextcloud from redis to valkey?
1. I stopped/disabled redis.
2. Installed valkey removing redis
3. Updated all configs per both wikis
4. started/enabled valkey (all good)
5. restarted httpd (all good)
6. attempted to access nextcloud (failed with the error above)
Anybody have any ideas how I can get nextcloud back up and running
with valkey? Worst case I'll try disableing redis/valkey altogether in
the nextcloud config and run without caching -- not optimal. It was
running perfectly with redis before the upgrade, so I'm stuck.
