why is nginx timeout-ing?

Question

Here is my timeout related nginx conf :

http { ... proxy_read_timeout 300; proxy_connect_timeout 300; proxy_send_timeout 300; ... } 

and my reverse proxy setup :

upstream node { server 127.0.0.1:2200; } server { listen 80; location / { proxy_pass http://node; } } 

I am posting a query to my webserver and nginx times out after 1 minute with the following message :

2021/07/16 14:35:42 [error] 881124#881124: *14744 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 172.68.144.214, server: , request: "POST /photos/download_photos HTTP/1.1", upstream: "http://127.0.0.1:2200/photos/download_photos", host: "myhost.com", referrer: "https://myhost.com/"

Output of sudo nginx -T :

Why is nginx not taking my setting into account ? Or am I missing something ?

Answer 1

There is one timeout that is missing
