time out tyring to activate plugin

Hello,

I have a strong dedicated server.

WP limit 64 MB to max 265 MB

Memory limit is 512 MB

max_execution_time = 500

max_input_vars = 10000

Still i cant get the api page where you need to fill in your name and email. My site is connected with cloudflare, but after loading and loading i get a cloudflare page that it could not connect with the host.

While i can perfectly browse the website on mobile, an other computer in the meantime. What could cause this issue? I’m running on PHP 8.2
