I'm encountering an issue with my Laravel project deployed on an AWS Ubuntu server. Recently, the application intermittently returns a 500 error after login. However, when I run php artisan cache:clear, the application starts working again. Currently, I have to clear the cache daily to prevent this issue. how to solve.
It sounds like the issue is related to stale or corrupted cache data. If clearing the cache fixes it temporarily, it could be due to an underlying caching problem, like a misconfigured cache driver or conflicting data.
did you check laravel.log file to identify specific errors?
@JussiMannisto Nothing show in laravel.log at time get server error i have checked laravel.log but there nothing show any error but after use this command sudo chmod 777 storage && php artisan cache:clear && php artisan config:clear it start working. Also i mention that i am using aws lightsail ubuntu server and also using laravel scheduler.
@mounak If you just chmod the directory, the files inside might still not be writeable. You have to check the file permissions too.
But 0777 is really insecure. That means any user can overwrite the files. You should instead make sure the files and directories are owned by your web server user, e.g. www-data or apache. Then you can use the typical 0644 for files and 0755 for directories.
If you still don't get any errors in laravel.log after that, it's an indication that something is going wrong before the framework finishes booting up. You should check your web server logs.
You should also run all artisan commands as the web server user. Otherwise some files and directories - particularly those inside storage/framework/ - may get created with the wrong owner. That could also explain your cache issues if you're using the file based cache driver.
@JussiMannisto cache_driver=file. should i run all this commad :
php artisan cache:clear
php artisan config:clear
php artisan route:clear
php artisan view:clear
