Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can 
Nextcloud version (eg, 20.0.5): 21.0.3
Operating system and version (eg, Ubuntu 20.04): CentOS 8.4.2105
Apache or nginx version (eg, Apache 2.4.25): httpd-2.4.37-39.module_el8.4.0+778+c970deab.x86_64

The issue you are facing:
After upgrading from 20.0.11 to 21.0.3, nextcloud internet check is no longer able to reach internet. My Nextcloud is behind a transparent Proxy (OpnSense + Squid) and the CA file of the proxy is appended to resources/config/ca-bundle.crt as in previous versions.
Yet , now I receive the following error and the Settings → Overview → Security & Setup Warnings fails with " * Error occurred while checking server setup"
nextcloud log shows:

Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Put the nextcloud behind transparent (http + https ) proxy
- Add the Proxy CA file to resources/config/ca-bundle.crt
- Generate a symlink that points to the CA file in the OS similar to this one:
[root@nextcloud nextcloud]# ls -l /var/www/html/865038e4.0
lrwxrwxrwx. 1 root root 49 27 окт 2020 /var/www/html/865038e4.0 -> /etc/pki/ca-trust/source/anchors/OPNsense-SSL.crt
- Add the following in the php.ini
[curl]
; A default value for the CURLOPT_CAINFO option. This is required to be an
; absolute path.
curl.cainfo=/var/www/html/865038e4.0
- systemctl restart httpd php-fpm

What is the difference between v20 and v21 ?
