502 Gateway on Fresh Install error

Ok so the solution is if you upgrade from php8.1 to php8.3 you need to change the sites available config to read the php-fpm8.3 sock instead of the php8.1 sock. Marking this as resolved as of now. but the tutorial might need to be upgraded to use 8.3 since 8.1 is not available via the package manager on ubuntu 22.04
