The Basics

Nextcloud Server version:

Nextcloud 33.0.0

Operating system and version:

#1 SMP PREEMPT Debian 1:6.12.75-1+rpt1~bookworm (2026-03-11)

Web server and version:

Server version: Apache/2.4.66 (Debian)

Reverse proxy and version:

nginx version: openresty/1.27.1.2

PHP version:

PHP 8.4.18 (cli) (built: Feb 24 2026 19:12:53) (NTS)

Is this the first time you’ve seen this error? (Yes / No):

yes

When did this problem seem to first start?

recently

Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)

OMV Container

Are you using CloudfIare, mod_security, or similar? (Yes / No)

No

Summary of the issues you are facing:

A message on the Overview page appears:

Configuration server ID
Server identifier isn’t configured. It is recommended if your Nextcloud instance is running on several PHP servers. Add a server ID in your configuration.

But there is an id set:

$ php occ config:system:get instanceid
oc6oc6hi85a5

How do we remove the warning concerning Configuration server id

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

Logon with administration right
navigate to Administration / overview

Server id != instance id. See Die Server-ID ist nicht eingerichtet - #8 by it-hecker or server/config/config.sample.php at cde3780f0133e67f6f4eaf57fcaa058ac9851732 · nextcloud/server · GitHub

I’d just like to offer a clarification here for other readers - I have exactly the same message, but when I asked Google, “How do I set a NextCloud Server ID?” the response that Google gives is wrong. Specifically, I see the following:-

A Nextcloud server ID (instance ID) is

automatically generated during installation and stored in the config/config.php file. You do not typically need to set this manually. If you are trying to configure the server's network identity or domain name, you should edit the trusted_domains in config.php to match your server's URL. 

How to Find or Change Your Server ID

If you need to change your server's identifier for migration or technical reasons:

1. Locate config.php: Usually found in /var/www/nextcloud/config/config.php or /var/snap/nextcloud/current/nextcloud/config/config.php.

2. Edit the file: Look for the 'instanceid' => '...' line.

3. Update/Set ID: Replace the generated string with a new one.

4. Save and Restart: Save the file and restart your web server (e.g., sudo systemctl restart apache2 or snap restart nextcloud).

If you look at the second element of the numbered list, it directs readers to the “instanceid” value, not a ServerID value.

I very much appreciate that the response and explanation was correct; I just wanted to explain why other people [like myself] may be getting confused - if we follow Google’s advice, then we all end up not understanding the nature of the error message.

Now that I understand more clearly, I re-asked the question of Google and then I gave the answer a “thumbs down” response - I would urge anyone else reading this thread, who came here via Google’s incorrect answer, to do the same.

Thanks for setting us straight.

Hi,

We have also upgraded to version 33 and are seeing this message. Nextcloud is running on three web servers for redundancy, and the message recommends configuring these settings, but the documentation is somewhat unclear.

How should this command be executed?

Yes, how to properly configure this parameter? In what file? In what section? What text to insert/edit?

I was having this issue as well, and while I understand it’s only an “info” message, I still wanted it removed so my overview is clean of notes.

Thanks to @daniarv’s response, I figured out that using occ to set the config value is sufficient, and using it removed the message.

occ config:system:set serverid --value=0

The above command was enough for Nextcloud to treat the value as filled (default is -1, and values between 0 and 1023 are considered non-empty)

Thank you @casraf.

A tip to others that come here and copy and past that command. The double dash is not formatted correctly. Or at least it is not two dashes. Took me a minute to see that one dash is slightly longer than the other.

Not sure what happened there, edited, hope it works now

Hi all,

I have the same problem:

Configuration server ID

Server identifier isn’t configured. It is recommended if your Nextcloud instance is running on several PHP servers. Add a server ID in your configuration.

but I don’t have shell access. Is there anything I can do from cPanel to remove the warning?

Ciao,

Max

P.S.

Apparently the occweb application is not supported for the last releases of Nextcloud so I don’t have that escape either.

First of all, as the message suggests, on a single server with a single PHP backend, which is what 99.999% of home and small-business users have, and what you definitely have if your Nextcloud is running on a basic shared hosting plan, you can safely ignore the message.

Regarding OCC Web, you might be able to force-enable it, and it may still work even though it is not officially supported for versions 32 and 33. However, that is not something you should rely on forever. It is only a stopgap, and it always has been. At some point, it may stop working entirely, and you might run into a real problem rather than just a cosmetic one. Then you would be stuck without shell access.

That is why I highly recommend paying the extra couple of bucks or so for a shared hosting plan with shell access if you absolutely need to run Nextcloud on shared hosting.

When it comes to cPanel, I’m not sure whether there is a workaround. It probably also depends on your hosting plan, because even the available features in cPanel can vary depending on the plan. However, it has been a few years since I last dealt with web hosting and hosting panels, so I can only say the following:

At the end of the day, you somehow need to get the line 'serverid' => 0, into Nextcloud’s config.php file to get rid of the message. If you cannot do it via the occ command, you will have to find another way to edit the file. There’s probably some way to do that on your web host. And if there really isn’t, as a last resort, you could try downloading the file via FTP or something, editing it locally, and then uploading it again.

You might also want to check the documentation or support section of your hosting provider’s website, or you could open a support ticket there.

Hi,

How should i deal with this command when using multiple web servers?
occ config:system:set serverid --value x

We have 3 Nextcloud web server where config.php is the same on all three servers.
Should we then set the serverid value manually in each config.php?

I have a ‘hot backup’ for my personal nextcloud server that runs on a separate system. When main goes offline, the other becomes primary and changes my domain’s DNS record. The data & databases sync between the two and everything work well.

In this instance, would I set two different server IDs?
