My Server configuration is
Moodle 3.6 stable ( I download the moodle version from https://download.moodle.org/download.php/stable36/moodle-3.6.tgz)
Fake SSL certificate (this is on my local machine).
Chmode 777 to all folder (codebase + moodledata directory).
Problem statement:- sometimes links are not working ( it throw the error "connection reset and page goes offline").
Initially, I thought it might be related to
1 response time ( for this I already increases the execution time on .ini file)
2. may be because of permission (I already set full permission for folders)
3. some misconfiguration mainly related to cache (I don't know how to handle this).
This normally occurred when I install any plugin (on upgradesettings.php file it goes to offline), that's why I thought it might be connected to execution time or related to permission, but I am not able to figure out.
does anyone know the reason and solution?
