upstream timed out .. how to set proxy_connect_timeout

[cloudsense]

Hi,

In my nginx error logs I have something like this

2024/06/20 22:05:37 [error] 75685#101233: *77740 upstream timed out (60: Operation timed out) while reading response header from upstream, client: A.B.C.D  server: www.example.com, request:  "GET / "..

I could not find any settings related to this in the GUI. On the config file, below location for the specific domain,  i have under the proxy_ settings  include 4f3bf9ec-0322-4045-b9bc-4b26f43e9ab7_post/*.conf entry.
I created the folder, created domain.conf file and put

proxy_connect_timeout 300;


but I still get the 60s error above.

What is the recommended way to set  proxy_connect_timeout  ?

Thanks
