Please, can somebody look at this config?
global
log stdout format raw local0 debug
stats timeout 30s

option httplog

timeout server 50000

bind *:15080
default_backend myback
backend myback
server site google.com:80 check
Why is this not working? If I try to visit 127.0.0.1:15080 it takes some time and then the url in a browser changes to www.google.com:16080 which obviously doesn't take you anywhere. The browser says: "This site can’t be reached - ERR_CONNECTION_TIMED_OUT".
So why doesn't it proxy to port 80 as one would expect?
The log entry does not tell much:
127.0.0.1:50871 [01/Jul/2019:14:39:45.879] app myback/site 0/0/20/84/104 301 681 - - ---- 2/2/0/0/0 0/0 "GET / HTTP/1.1"
Haproxy version:
HA-Proxy version 2.0.0-4fb65f-8 2019/06/19 - https://haproxy.org/
EDIT:
I somehow solved the problem by trial & error..
Actually, HAProxy is working as expected and proxying your request to google. Google, however, sees that the host header is 'Host: 127.0.0.1:15080', and responds with a 301 redirect to www.google.com:15080. You can see this without setting up HAProxy by doing:
$ curl -I -H 'Host: 127.0.0.1:15080' google.com

If you want to set up a very basic proxy to google, you need to make sure your host header matches and that you are sending requests via https.
