Issue after upgrading to 25.0.0

Hello everybody,
After upgrading Nextcloud to 25.0.0 i’ve an issue with Collabora Online - Built-in CODE Server.
The problem is that I can’t open the files (writer, calc) on the web browser but i must download it and then upload.
The same issue occured when I upgrade to version 23.0.0.
Thanks in advance for your support!

I am actually having the same problem. Don’t use it a lot so not too big of a problem. Still weird. Files just download and don’t open in the editor. Using the built in collabora and the nextcloud office apps

I actually experienced this with two different setup:
Old one
Linode VPS
Ubuntu 2204 and Apache WITHOUT reverse proxy
Nextcloud 25
Worked fine before upgrade!

But I just went to docker
Fresh Linode vps. Installed docker compose, portainer, nginx proxy manager, NC 25 uses 8080 which is mapped to 80.

Must be missing something obvious :slight_smile:

version: '2'

@lanhouse.tgn did you manage to fix this?

I confirm. The upgrade from 24.x (stable) to 25.0.1 (stable) has effectively killed this feature.
occ check and occ status are OK.
The install is on the VM with LAMP stack, no snap (Ubuntu 20.04 upgraded to 22.04).
I don’t find anything related to this problem in Administration settings / Logging.
What PHP modules are required for this feature?

I have disabled and removed both “built-in CODE collabora online” and “Nextcloud office” applications, then re-downloaded and enabled them. Some time later it started working again. Very strange…

I gave it another try as well but still not opening files online. So strange.


I have the same problem here. Upgraded from 24.x stable to 25.0.1 and from that moment on document files are downloaded instead of opening the collabora editor. I did update to 25.0.2 today but same result.
My installation is: PHP 7.4 (tried also 8.0 and 8.1), no disabled_functions, no docker.

Tried to use one of the demo servers in the nextcloud office settings and then it works again. But with builtin CODE server it does not work.

It seems to be an issue that Nextcloud does not recognize that a collabora server is available when using the builtin CODE server:

  1. Select to use a demo server in Nextcloud Office admin settings.
  2. Reload files app (use another browser tab).
  3. Opening documents works (collabora with demo watermarks opens).
  4. Go back to Nextcloud Office admin settings and switch to builtin CODE server.
  5. Go to files app without reloading the page.
  6. Opening documents works (collabora without demo watermarks opens).
  7. Reload file app page.
  8. Opening documents does not work (direct download instead of collabora opening the file).

Best regards,

This is exactly the behavior I’m seeing as well. I replicated your steps exactly.

Even more frustrating for me: I run two nextcloud instances which, apart from branding, use the same setup, running the same version of nextcloud, same version of PHP, same applications, and Office works perfectly every time on one of them but not on the other.

I have the same issue with the built-in CODE server. Access to documents results in either download or a failed connection to the document. Backend checks are green.

One thing there was new after the update was an error that I needed to whitelist the IP for WOPI. I set that to in the Office settings screen.

Error after failed loading: Nextcloud Office could not be loaded. Please retry later.

I have the exact same issue running the built-in CODE serve on Nextcloud 25.0.2

Nextcloud Hub 3 - 25.0.2

Everything was working without problem on Nextcloud 24 and after successful update to NC25 AIO - Nextcoud office is not working anymore with message:


I tried to restart docker container and it didn’t help.

Is there any fix to this annoying issue…or I should go back to NextCloud 24 AIO?
Definitely in future I will not update NextCloud so easily as new versions bring problems like this one.

Hi, can you follow How to debug problems with Collabora and/or Talk · Discussion #1358 · nextcloud/all-in-one · GitHub?


Thank you for your replay szaimen, I will try it as soon as I get home and report here what happend!

I tried right away and adding , Allowed list for WOPI requests and everything works as expected!

Only downside is that this is not secure as you allow all ip-addresses to connect by doing so.

Thank you very much!

I’m using the integrated CODE server plugin but I’m not able to open any documents, user is going to be disconnect and connection goes in loop and in logs I see a lot of 400 HTTP error code. This happens after upgrading from nextcloud 24 to nextcloud 25.

I’ve updated PHP to 8.0.27-1, now it works again.

Same problem, now I’ve cleaned /tmp directory and restart php-fpm service (systemctl restart php-fpm)

Same here. like collabora is not integrated anymore even if activated. Creating a new document has no option to create office or excell sheet
opening csv file is only downloading, not opened anymore.
seems that latest update broke nextcloud office integration

updating from php7.4 to php8.0 solved issue.
