Attempting to load any file on Nextcloud fails

[csolisr]

Describe the bug

When attempting to load any LibreOffice file on Nextcloud, the system consistently fails to load it with an error message

Context

• Hardware: Intel NUC
• YunoHost version: 4.2.6.1
• I have access to my server: Through SSH, webadmin, direct access
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: yes
  • If yes, please explain: Followed additional steps described in this issue, see below
• Using, or trying to install package version/branch: Collabora 6.4.10

Steps to reproduce

• Install Nextcloud and the Collabora plugin
• Install Collabora, configure it to use Nextcloud's domain
• In the settings file at /etc/loolwsd/loolwsd.xml, configure limit_virt_mem_mb, limit_stack_mem_kb, limit_file_size_mb, limit_load_seconds, limit_convert_seconds, and max_file_size to 0 to prevent timeouts
• Configure Nextcloud via the Collabora plugin to connect to the server
• Open any LibreOffice file via Nextcloud (tested with ODS and ODT files)

Expected behavior

The file should load after a certain amount of time, but it never does. Instead, a popup appears with the following message:

Failed to load the document. This document is either malformed or is taking more resources than allowed. Please contact the administrator.

Same thing here. Also use a similar configuration you describe in the Bug #49. The office.example.com is the collabora and the nextcloud.example.com is the nextcloud. Let me know if you need additional info.

Best

Out of interest, what is your language setting in Nextcloud?

[csolisr]

Spanish (Latin America) - I'll try setting it to English to see if it changes anything

[csolisr]

Just tested, switching the language to English does fix the issue for me

@csolisr Thank you. See also https://github.com/nextcloud/richdocuments/pull/2054 The fix in LOKit will follow soon.
