What if i increase all the numbers in PHP-FPM Pool Options

My website is always receiving 522 Connection timeout. I upgraded my vps to dedicated server but it still the same.

So i found this solution online: PHP-FPM tuning. What will happen if i increase it to the very maximum?

This is my configuration: PHP-FPM Pool Options Max Requests 1000000000000000 Process Idle Timeout 1000000000000000 Max Children 1000000000000000
