Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 20.0.5): 26.0.0
Operating system and version (eg, Ubuntu 20.04): Ubuntu 22.04.2 LTS
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.52
PHP version (eg, 7.4): 8.2.5

The issue you are facing:
I can login and browse and download files. But when I try upload a file, I am facing a HTTP 500 with connection refused. I can change files without issues, like modifying .md files as long as I do it in the interface. I suspects this is caused by apache config somewhere.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Try upload a file - any file - at any destination folder.

The output of your Nextcloud log in Admin > Logging:

Nothing from the last 7 months.

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):


The output of your Apache/nginx/system log in /var/log/____:

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

Nothing of interest.

Correction: Also issues when trying to download a file.

I have Require all granted in my apache config for NC as well.

Turns out it was Redis failing. Only visible in the php-fpm service journalctl. Silly me to NOT check Redis and quickly assume it is Apache denying access.

ok but what did you do then? I have the same error as you, and have just added memcache.locking to redis, as was suggested since upgrading to 27.0.

I setup APCu, then re-did my Redis.
