I have developed a website in PHP Laravel. It is working fine but there is some core web vitals issues. I have tried to fix it but it has not done all. LCP, FCP INP (interaction to next paint) and TTFB (time to first byte). These core web vitals factors are stills red and speed index value is also red.
I have reduced CSS and Javascript manually. There are no images in this website. I have put my all efforts but still facing these issues. The website (https://www.rndgenerator.com/).
Can anyone please test the site and guide me how to resolve these issues. Thank you.
