I have installed a Moodle 3.4 website on CentOS 7 and nginx 1.17 (on VMWare EXSi 6.7). It has more than 200 students. The Teacher has started to use Moodle Mobile app for students recently. They are having problem when working with the Moodle app. It does not show files and images as usual. And this is random (users and the content) and not for all the students. Could not find any issue from the server but following error. Also for YouTube videos they get error as I the attached Image.
FastCGI sent in stderr: "Unable to open primary script: /path/to/moodle/local/mobile/check.php (No such file or directory)" while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: lms.xxx.xxx.xxx, request: "POST /local/mobile/check.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm/php-fpm.sock:", host: "lms.xxx.xxx.xxx"
Therefore I have upgraded the Moodle website to 3.8. But still I am having this error.
When using the PC all the content shows as usual. Your support highly appreciated on this problem.
