No input file specified. CPANEL/PHP

My Laravel application has been on my Cpanel for over 3years.
Today it started throwing Error No input file specified. when you visit my website.

I move the same code to a subdomain text.lamxxx.com and it work FINE.
But on my main domain is still throwing No input file specified.
I have been troubleshooting for over 24hrs.I checked the Server Log, check laravel log etc. But The website is still down.
