Is this the first time you’ve seen this error? (Y/N):N

Steps to replicate it:

  3. error occur

The output of your Nextcloud log in Admin > Logging:

None

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

None

The output of your Apache/nginx/system log in /var/log/____:

[error] 19184#19184: *154 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 120.84.12.191, server: pan.tamabi.de, request: "GET /settings/ajax/checksetup HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "pan.tamabi.de"

I am pretty confuse, the php-fpm shuld work fine or I will not able to click in the website.:thinking:. There is no error on php-fpm log and nextcloud log. Just find this in nginx log.

this error only happen when using this function.
