Hi everyone.
In my installation the following problem appeared suddenly.
This error appears in the system log:
[internet_connection_check] Error: Cannot connect to: www.nextcloud.com
GET /index.php/settings/ajax/checksetup
Detailed as:
GuzzleHttp \ Exception \ RequestException: cURL error 60: SSL certificate problem: certificate has expired (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://www.nextcloud.com/
My installation is in a Shared Hosting so I do not have access to the common folders that are in Linux.
I have tried doing a fresh install but I get the exact same error.
I have never gotten this error before. Consequently I cannot see the list of Apps from https://apps.nextcloud.com/
My version is 21.0.4. On PHP 7.4
I appreciate your help because it is important that this problem can be solved properly.
