I want to set up nginx as a forward proxy - much like Squid might work.
This is my server block:
server {
listen 3128;
server_name localhost;
location / {
resolver 8.8.8.8;
proxy_pass http://$http_host$uri$is_args$args;
}
}
This is the curl command I use to test, and it works the first time, maybe even
the second time.
curl -s -D - -o /dev/null -x "http://localhost:3128";
http://storage.googleapis.com/my.appspot.com/test.jpeg
The corresponding nginx access log is
172.23.0.1 - - [26/Feb/2021:12:38:59 +0000] "GET
http://storage.googleapis.com/my.appspot.com/test.jpeg HTTP/1.1" 200 2296040
"-" "curl/7.64.1" "-"
However - on repeated requests, I start getting these errors in my nginx logs
(after say the 2nd or 3rd attempt)
2021/02/26 12:39:49 [crit] 31#31: *4 connect() to

What might be causing these issues after just a handful of requests? (curl
still fetches the URL fine)
