Nextcloud 27 upgrade breaks Nextcloud Office

[karlemilnikka]

Steps to reproduce

1. Upgrade to Nextcloud 27 by following the official instructions.
2. Try opening a Nextcloud Office document or create a new one.

Expected behavior

I’ve run into a very strange Nextcloud Office issue after upgrading to Nextcloud 27 (Nextcloud AIO 6.1.1). Downgrading solves the issue, but I thought I should mention it in case others run into the same issue.

After upgrading, I can no longer open documents in Nextcloud Office. If I create a new document, I get an error message stating that “document loading failed”. If I try to open an existing document, I get a partially loaded Nextcloud Office interface with a document stating “cannot decrypt this file, probably this is a shared file. Please ask the file owner to reshare the file with you”.

This issue is however not affecting templates. I can open templates without any issues. Everything seems to be in order in the settings app as well (settings/admin/richdocuments). Allowing all IP addresses in the WOPI requests field doesn’t solve the issue.

cc @juliushaertl do you know if something has changed on collabora side in code:23 that needs changes on AIO side?

@karlemilnikka do you have something related in collabora or nextcloud logs?

I don't think we had a related change in richdocuments but this sounds like nextcloud/richdocuments#2996

Made a quick check on my instance - Office works for me on my mobile browser.
Will check on desktop if everything works.
Oh, it was an odt file i tried.... Will create an docx and edit this post.

Thanks Julius! :)

Duplicate of nextcloud/richdocuments#2996 then.

Now that Nextcloud AIO automatically upgrades the Nextcloud container to 27, more users are experiencing this issue.
