Support intro
Nextcloud version (eg, 20.0.5): Nextcloud 25.0.2
Operating system and version (eg, Ubuntu 20.04): OpenWrt 22.03
Apache or nginx version (eg, Apache 2.4.25): Caddy 2.6.2
PHP version (eg, 7.4): 8.1 (FPM, ZTS)
The issue you are facing:
I successfuly installed NextCloud on my OpenWrt device - on a FriendlyElec NanoPi R6s, which is a 4+4 core ARM board with integrated graphics; it’s pretty beefy. I installed NextCloud with MariaDB (15.1) and run it behind Caddy + PHP-FPM. It works, really well in fact, with no issues left in the dashboard. However, I can not seem to be able to use the search bar to find any of the apps - like Deck - to install them to my instance. And I would like to know why that is. 
Is this the first time you’ve seen this error? (Y/N): No. Then again, my previous instances used Docker Compose.
Steps to replicate it:
- Install NextCloud
- Make sure all checks pass in Admin dashboard
- Go to Profile Icon → Apps and only observe the preinstalled apps.
- Use the search icon and type any of the known app names only to see that nothing was found.
The output of your Nextcloud log in Admin > Logging:

There are a few more like this, including nextcloud.com et cetera.

Posted above.
Edit:
After a lot of back and forth with documentations of cURL, Guzzle and trial-and-error, I eventually figured out the problem, which creates a new one:
# curl --compressed --head "https://apps.nextcloud.com/api/v1/apps.json"
curl: option --compressed: the installed libcurl version doesn't support this
curl: try 'curl --help' for more information
The cURL on my server does not support compression - which quite likely trips Guzzle, which tries to make a compressed request. Thus, the content encoding is bound to be wrong.
How can I force Guzzle into not doing that? Thanks!
