web - nginx serves, the front-end text data exceeds 300 words, cannot be saved, and the server reports a 500 error!

Question

nginx is doing services. The front-end text data exceeds 300 words and cannot be saved. The server reports a 500 error. Data smaller than 300 can be saved normally. Is there something wrong with the configuration? Please ask all experienced drivers

nginx configuration has been set

proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host            $http_host;
proxy_buffer_size 1024k;
proxy_buffers 32 1024k;
proxy_busy_buffers_size 1024k;

Answer 2

500 is the code error. First take a look at the code to see if there is an error in the code processing the request data. Or post the 500 error message.

Answer 3

Please take a look at the error log, otherwise it will be difficult to determine. If it is determined that it is a word count problem, take a look at what type of text your database uses to save text. It may be that the length is not enough to save it.

Answer 4

You can’t memorize nginx. Please post the code and see. 500 is usually a program error.

Answer 5

It should be restricted by your php-fpm configuration. It is not nginx configuration.

Answer 6

Check mysql restrictions
