The Basics

Nextcloud Server version (e.g., 29.x.x):
- 29.0.1
Operating system and version (e.g., Ubuntu 24.04):
- Debian
Web server and version (e.g, Apache 2.4.25):
- Apache 2.4.25
Reverse proxy and version _(e.g. nginx 1.27.2)
- unknown
PHP version (e.g, 8.3):
- 8.2
Is this the first time you’ve seen this error? (Yes / No):
- No
When did this problem seem to first start?
- few days before this posting, and similar issue in 2023
Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
- manual over shared hosting
Are you using CloudfIare, mod_security, or similar? (Yes / No)
- unknown, likely not

Summary of the issue you are facing:

During manual upgrade and calling the instance in any browser I reach the page “Nextcloud will be updated to version 29.0.16” and I cannot press the “Start update” button. When I hover over the button with my mouse it turns white and I cannot click to start the update.

I was going to update from 29.0.1 (1) to 29.0.16, and then (2) to 30.0.13 and finally (3) to 31.0.7, but I’m stuck on step (1).

A similar issue happened with a previous update in 2023 to 27.1.4, but I was able to use another browser (Ungoogled Chromium) and it worked, so I didn’t think anything of it. Using the method described below, I have successfully updated my nextcloud on shared host several times.

Steps to replicate it (hint: details matter!):

Backed up my existing Nextcloud Server database, data directory, and config.php file (using Filezilla as FTP and AlternC web hosting server mgmt software)
Downloaded the 29.0.16 release from Nextcloud server changelog
Disabled cron job in AlternC
Changed maintenance mode to true in config.php and uploading via Filezilla.
Renamed current NC directory (e.g nextcloud-old)
Extracted 29.0.16 zip and uploaded to shared host server via Filezilla
Copied config file to new NC folder
Deleted config file from nextcloud-old
Moved /data/ folder from nextcloud-old to new NC folder
Changed maintenance mode to false by editing PHP and uploading using Filezilla.
Called nextcloud instance in browser (e.g. Firefox, Chrome) visiting website (e.g. www.mynextcloud.com/cloud/)
Moved mouse to press “start update” button.
Button turns white and text disappears. Cannot click “start update” button. Update does not start.

My nextcloud is in a subfolder of the domain (e.g. www.mynextcloud.com/cloud/ instead of www.mynextcloud.com), which might be an issue that I don’t know how to solve. For this example I used the output from Librewolf but I have tried it on multiple browsers, including on a windows machine that had no extensions with the same result.
I replaced the [server IP address] in this output.

Web server / Reverse Proxy

Can't find this.

Configuration

Nextcloud

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

<?php
$CONFIG = array (
  'instanceid' => '[the instance ID]',
  'passwordsalt' => '[the password salt]',
  'secret' => '[the secret]',
  'trusted_domains' => 
  array (
    0 => '[server domain]',
  ),
  'datadirectory' => '/var/alternc/html/t/[subdomain]/www/[server domain]/cloud/data',
  'dbtype' => 'mysql',
  'version' => '29.0.1.1',
  'overwrite.cli.url' => '[server domain]/cloud',
  'dbname' => 'tnm',
  'dbhost' => '[database location]',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'mysql.utf8mb4' => true,
  'dbuser' => '[database username]',
  'dbpassword' => '[database password]',
  'installed' => true,
  'maintenance' => false,
  'theme' => '',
  'loglevel' => 0,
);

I’m not sure what parts are identifiable information, so I took a guess and [replaced it].

Apps

The output of occ app:list (if possible).

Using shared host, I don’t know where this is. If it’s useful, the update webpage of my instance says this:

The following apps will be updated:

Files (files)
OAuth 2.0 (oauth2)
Text (text)

These incompatible apps will be disabled:

gpoddersync (gpoddersync)
quota_warning (quota_warning)

In my last update I wanted to try gpoddersync, but I never ended up needing it so I was wanting to drop it during this upgrade. I figured I didn’t really have to do anything special to remove it when manually upgrading.

Tips for increasing the likelihood of a response

Use the preformatted text formatting option in the editor for all log entries and configuration output.
If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.

Thanks for any and all help.

You can try the update by terminal:

cd /var/www/nextcloud/updater
sudo -u www-run php8.3 updater.phar

Gammonsteak · August 18, 2025, 10:38am

My apologies, I wasn’t explicit.
I’m running Nextcloud on shared hosting and don’t have access to the terminal.
EDIT: I have edited the title to reflect this.

scubamuc · August 18, 2025, 12:50pm

ideally contact your provider support.

Gammonsteak · August 19, 2025, 3:01am

I contacted my provider support (which is very limited), and they fixed some permissions and ran the update via terminal, and it seems to work and my folders appear to sync, but it has introduced a new problem.

When I visit the instance, the login page appears but no popup to input username or password. I checked my nextcloud.log after setting it to loglevel = 1, and I see “suspicious_login_detected” from app “suspicious_login”. It also says “message”:"Notification was not parsed by any notifier.

My provider is not located in my city, and so I wonder if when they updated it on their machine it only recognized their IP. How do I fix this to be able to login?

jtr · August 19, 2025, 5:14pm

Are you using CloudfIare, mod_security, or similar? (Yes / No)
unknown, likely not

Are you sure your provider isn’t using mod_security or Cloudflare or something? That’s a typical cause of unexplained front-end issues.

Please re-check your browser inspector again (like you did in the original report; instructions are in the support template). While reproducing the behavior monitor first the Network tab for anything that fails to load. Then the Console tab for any errors.

The suspicious login app just notifies about suspicious logins; it doesn’t prevent logins.

Gammonsteak · August 19, 2025, 6:58pm

I sent them an email to confirm, I’m still unsure.

Please re-check your browser inspector again (like you did in the original report; instructions are in the support template). While reproducing the behavior monitor first the Network tab for anything that fails to load. Then the Console tab for any errors.

Console tab:

Network tab:

One thing I noticed is I had a custom theme and color for the nextcloud background (just a different default color) and it briefly shows up and then reverts to the default blue background. Not sure if that’s relevant.

The other thing to note is the network tab Domain column it shows the domain I use (e.g. www.mynextcloud.com) but doesn’t show the subfolder it’s actually in (e.g. www.mynextcloud.com/cloud/). I also am not sure that’s relevant or not.

Gammonsteak · August 20, 2025, 3:30am

My provider got back to me, and said they are not behind Cloudflare, and mod_security is not enabled.

They tried to see if making a domain without the “/cloud” subfolder would resolve anything, but it still did not fix the issue.

I remain without login screen.
