I updated my Ubuntu 24.04 and my WordPress stopped loading images of size 1.3MB and higher.
I fixed this by adding the following:
client_max_body_size 32M;
to Nginx configuration.
My php.ini parameters were the following:
upload_max_filesize = 32M
post_max_size = 32M
memory_limit = 128M
max_execution_time = 30
max_input_time = 60
