[Solved] When PostgreSQL writes data to Excel, there is a failure your, nginx error handling

Today’s development colleagues read the data from PostgreSQL and wrote it to excel. Due to the large amount of data, the development colleagues wrote the code that was not good enough and the speed was too slow, so there was a problem. I found the following information and modified the configuration of nginx to solve this problem. The detailed errors are as follows:

An error occurred.

Faithfully yours, nginx.


Change localhost in nginx configuration file to IP


Modify the hosts file and add localhost

    proxy_pass http://localhost:8080  # change to

Set connection time

proxy_ connect_ timeout 300; # The connection timeout between nginx and back-end server (proxy connection timeout)
proxy_ send_ timeout 300; # Back end server data return time (proxy sending timeout)
proxy_ read_ timeout 600; # After successful connection, the response time of back-end server (proxy receiving timeout)

is shorter

After modifying the configuration file, reload the configuration file

nginx -s reload
