Cannot open doc, docx, xlsx, odt, ods, txt files

[R8s6]

Expected behaviour

Able to view and edit common office documents, such as doc, docx, odt, xlsx, ods, txt files, with Nextcloud's built-in viewer.

Actual behaviour

Cannot view or edit common office documents, such as doc, docx, odt, ods, txt files.
It shows a white page, then with an error:
cURL error 3: malformed (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

Txt was supported a while ago, but lately it couldn't be opened any more.

Steps to reproduce

Server: snap 19.0.2snap1
Client, iOS 3.06
Open up a doc, docx, odt, ods, txt file,

Reasoning or why should it be changed/implemented?

These files are very common in an office environment, so it's probably expected that these files can be opened by the built-in viewer.
Your competitor Dropbox can open them.

Update:

As of 2021-06-15,

• txt: it opens, but it takes about 15 seconds
• office files such as doc, docx, odt, ods: still cannot open. Also, the GUI doesn't have a "go back" option, when error occurs, one has to restart the iOS Nextcloud app to continue using it.

Client: official iOS app, v3.4.2.0

For me ODS/XLSX files do not open. These files simply give a message saying that an error occured while opening the file. (sometimes it doesnt give error and just sits at "loading spreadsheet") XLS file does open. Additionally - from a desktop computer all files open without issue.

OS - Ubuntu LTS 20.04
PHP 2:7.4+75
Nextcloud 21.0.3
Document server 0.1.11
Onlyoffice 7.0.2
ios app 4.0.4 (same error occurs when opening via the web browser and not using the app)

I've run in to this as well, with app version 4.0.6.0 (iPhone Xr running iOS 15.0.1) and server version 22.2.0. It's an excel file created by a python script that I wrote, using XlsxWriter. It's just a couple tabs, with data from my Kodi instance. I can share it if it'd help y'all debug the app. It opens fine in Numbers on the iPhone.

I have fixed this issue by disabling the OnlyOffice extension 🤔 Thats of course not a great solution but maybe helps diagnosing the issue further.
