Hello,
I have a quite big problem with Prestashop under Haproxy.
When I try to use advanced features, I receive 502 errors : 502 Bad
Gateway - The server returned an invalid or incomplete response.
Error log give me something like that :
Nov 22 20:03:10 localhost haproxy[29665]: 1.2.3.4:15870
[22/Nov/2009:20:03:09.713] www srv-www1 25/0/0/-1/985 502 8396 - -
PHVN 20/19/15/9/0 0/0 {domain.tld} "POST
/boutique/urladmin/index.php?tab=AdminCatalog&id_category=1&token=bc27a5d070551ac1e057b5d54fd9dd78
HTTP/1.1"
Without Haproxy, it works fine.
I know Haproxy give 502 errors when a bad header is sent by the app
(like 'Location : index.php' instead of 'Location: index.php'), or if
the backend server unexpectedly close the connection (honestly, I
would prefer a more verbose message, who explains exactly what is the
problem).
But here, I don't see any errors like that.
Do you have some ideas in order to debug that ? More verbose logs, tests, ...
I tried with -d mode, but I can't find any 502 error ...
I use Haproxy v. 1.3.22.
Thanks in advance,
Neri
