How to resolve timeouts when nginx accesses backend servers?

If Nginx is timing out while accessing the backend server, you can try the following solutions:

  1. timeout for establishing a connection in a proxy server
  2. timeout for sending data to the proxy server
  3. timeout for reading a response from the proxied server
proxy_connect_timeout 60s;
proxy_send_timeout 60s;
proxy_read_timeout 60s;
  1. Adjust the timeout configuration of the backend server: If Nginx is proxying to another server, you can check the timeout configuration of the backend server to ensure that the timeout time is long enough.
  2. Increase the number of worker processes in Nginx: In the configuration file of Nginx, you can increase the value of the worker_processes parameter to increase the number of worker processes in Nginx, in order to improve its ability to handle concurrent requests.
  3. Check the performance of the backend servers: If the backend servers are experiencing high load, it may lead to longer response times. You can assess the performance of the backend servers, add hardware resources, or optimize the code to improve performance.
  4. Utilize caching: If the data returned by the backend server does not change frequently, consider using Nginx’s caching feature to store the response and reduce the number of requests to the backend server.
  5. Check network connection: If there are any network issues between Nginx and the backend servers, it may result in timeouts. You can check the network connection status to ensure it is working properly.
  6. Utilize load balancing: If there are many backend servers, consider using Nginx’s load balancing feature to distribute requests to multiple backend servers, in order to enhance the system’s processing capacity.

The above are some common solutions, which should be adjusted and optimized according to the specific situation.
