While google (or any other robot) is crawling my website developed using Laravel, it gets 503 Server Unavailable error. I can visit my website without any problem and do not get any error: http://www.kurumyonetimsistemi.com
How can I fix this problem?
Edit:
503 error is because I am redirecting not found pages to a custom page. If I remove this redirect, robots get 500 Internal Server Error. But I can display my website on a browser without problem.
