- NGINX
Reverse proxy and version _(e.g. nginx 1.27.2)
- nginx/1.18.0
PHP version (e.g, 8.3):
- 8.2
Is this the first time you’ve seen this error? (Yes / No):
- yes
When did this problem seem to first start?
- After 30.0
Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
- I don’t know anymore
Are you using CloudfIare, mod_security, or similar? (Yes / No)
- No

Summary of the issue you are facing:

Connection problem: we are not being redirected, but we have to refresh to connect.

My Problem :

Nothing really shocking in the logs. There are some entries to the upgrade, and it seems to have passed successfully.

I am not familiar with theming, is it possible that for that reason some things are just not seen (text or stuff having the same color as the background or are marked with hidden?).

And is it normal to have office and onlyoffice installed at the same time? Such a thing would be my second guess that some app is tricking you by hiding some things.

Over the last versions there were a few changes, so some apps and/or some themes might need some adaptation. If you know at which version you have started seeing problems, you can try to dig deeper what exactly has changed.

Hi @gabsamw,

two separate things are going on, and you already pointed at one of the real culprits. Worth fixing them in order.

1. PHP runs out of memory, and that is what blanks your pages. Your log has an explicit fatal:

gabsamw:

2026/07/16 10:30:04 [error] 793735#793735: *35 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 285066024 bytes) in /var/www/nextcloud/updater/index.php on line 881" while reading response header from upstream, client: 10.8.0.3, server: , request: "POST /updater/ HTTP/1.1", upstream: "fastcgi://unix:/run/php/php8.2-fpm.sock:", host: "10.8.0.8"

134217728 is 128 MB, so memory_limit is at the old default. Nextcloud’s minimum is 512 MB, and more is fine. The apps page and the admin pages are Vue views that call an API; when that request builds the full list of your 60-plus apps and dies at 128 MB, the API returns a 500 and the page renders empty, which is exactly your blank /settings/apps (only the theme logo left) and the empty logging page. The checksetup upstream timeout in the nginx log is the same request giving up. Raise it in both php.ini files, because the web path and occ/cron use different ones. On Ubuntu 24.04 with PHP 8.2 they are:

PHP-FPM pool: /etc/php/8.2/fpm/php.ini → memory_limit = 512M (or higher), then reload php-fpm
CLI: /etc/php/8.2/cli/php.ini → memory_limit = 512M (or higher), so occ upgrade and cron do not hit the same wall

2. The two force-installed apps you spotted have to go, and one of them cannot run on 34 at all. You have this in config.php:

That flag bypasses the compatibility check, so both run despite declaring a far older maximum. I looked at their code:

files_external_ipfs declares max Nextcloud 18 and was last touched upstream in 2020. Its appinfo/app.php uses the legacy OC_App::loadApp() / \OC::$server->query() bootstrap, and that whole appinfo/app.php mechanism was removed in Nextcloud 32. Its Application class does not implement IBootstrap either, so on 34 nothing loads it. In other words it can no longer register its storage backend at all; it is dead weight on your instance.
webhooks (kffl) declares max 26. You do not need it: Nextcloud ships its own webhook_listeners app (“Nextcloud Webhook Support”) in core since version 30, so the third-party one is redundant on 34.

Disable both and clear the overwrite:

cd /var/www/nextcloud
sudo -u www-data php occ app:disable files_external_ipfs
sudo -u www-data php occ app:disable webhooks
sudo -u www-data php occ config:system:delete app_install_overwrite

app_install_overwrite is meant for the rare case of a still-working app whose maintainer just has not bumped info.xml yet, not for apps 16 and 8 major versions out of date. These two are the prime suspects behind the failed config check and the repair errors on oc_appconfig/oc_jobs.

3. You have both Office apps enabled. As @tflidd said, office and onlyoffice are active at the same time (ONLYOFFICE shows in your admin menu). Two document editors registering handlers for the same file types collide. Keep the one you use and disable the other.

Then re-check the upgrade. After raising memory and disabling those apps, run:

sudo -u www-data php occ upgrade
sudo -u www-data php occ status

If occ status reports no pending upgrade and the two apps are gone, the admin and apps pages should (hopefully ) come back. The “dirty table reads” during repair most likely came from the upgrade steps dying on the memory limit, so they should not recur once memory is raised.

Two nginx log lines you can ignore:

gabsamw:

2026/07/16 10:28:59 [error] 793735#793735: *99 access forbidden by rule, client: 10.8.0.8, server: , request: "GET /data/.ncdata HTTP/1.1", host: "10.8.0.8"
2026/07/16 10:29:36 [error] 793735#793735: *117 access forbidden by rule, client: 10.8.0.8, server: , request: "GET /.well-known/webfinger HTTP/1.1", host: "10.8.0.8"

access forbidden for /data/.ncdata is correct, your data directory must not be reachable over the web, so blocking it is the intended result. The /.well-known/webfinger 403 is a missing well-known location block in your nginx config (see the Nextcloud nginx example); it only triggers a setup warning, not the crash.

h.t.h.
